Step 1: Convert the Mixed Number to an Improper Fraction
The first step in solving this equation is to convert the mixed number 7 1/4 into an improper fraction. Mixed numbers, which combine a whole number and a fraction, can be challenging to work with directly in algebraic equations. An improper fraction, where the numerator is greater than or equal to the denominator, provides a more straightforward format for mathematical operations. Converting the mixed number will allow us to combine terms and isolate the variable y more easily. This is a crucial step as it simplifies the equation and sets the stage for further manipulation. Understanding how to convert mixed numbers to improper fractions is a fundamental skill in mathematics, and mastering this technique is essential for success in algebra and beyond. The conversion process involves multiplying the whole number by the denominator of the fraction and adding the numerator. The result becomes the new numerator, while the denominator remains the same. This process ensures that we maintain the value of the number while expressing it in a more workable form.
In the case of 7 1/4, we multiply the whole number 7 by the denominator 4, which gives us 28. Then, we add the numerator 1 to this result, giving us 29. This 29 becomes the numerator of our improper fraction, and the denominator remains 4. Thus, the mixed number 7 1/4 is equivalent to the improper fraction 29/4. This transformation is a cornerstone of simplifying the equation and bringing us closer to solving for y. By converting to an improper fraction, we've taken a significant step towards isolating the variable and finding its value. The ability to move between mixed numbers and improper fractions fluently is vital for anyone tackling algebraic equations involving fractions. It not only simplifies calculations but also reduces the likelihood of errors. Therefore, let's proceed with this converted form, knowing that we have set a solid foundation for the subsequent steps.
So, 7 1/4 is converted to 29/4. Now, our equation looks like this: y + 5/6 = 29/4. This seemingly small change has a significant impact on the ease with which we can proceed. With both sides of the equation now expressed as fractions, we can focus on isolating y using the principles of algebraic manipulation. This conversion is a perfect example of how a simple transformation can unlock the solution to a more complex problem. Let's move forward and continue our journey to solve for y, armed with this valuable tool.
Step 2: Isolate y by Subtracting 5/6 from Both Sides
To isolate y, we need to subtract 5/6 from both sides of the equation. This is a fundamental principle of algebra: whatever operation you perform on one side of the equation, you must perform on the other side to maintain equality. Subtracting 5/6 from both sides will effectively cancel out the + 5/6 on the left side, leaving y by itself. This is the core concept of solving for a variable – to get it alone on one side of the equation. This step is crucial as it directly advances us towards the solution. Understanding and applying this principle is essential for solving any algebraic equation. It demonstrates the importance of balance and consistency in mathematical operations. By subtracting the same value from both sides, we ensure that the equation remains true, while simultaneously moving closer to finding the value of y.
This process of isolating the variable is not just about finding an answer; it's about understanding the underlying mathematical relationships. Each step we take is a logical progression, guided by the principles of equality and algebraic manipulation. Subtracting 5/6 from both sides is a clear application of these principles. It's a deliberate action, aimed at simplifying the equation and revealing the value of the unknown. This technique is widely applicable in mathematics and forms the basis for solving more complex problems. The ability to isolate variables is a powerful tool that will serve you well in various mathematical contexts.
So, subtracting 5/6 from both sides of the equation y + 5/6 = 29/4, we get: y = 29/4 - 5/6. Now, we have y on one side and an expression involving fractions on the other. The next step is to simplify this expression by finding a common denominator and performing the subtraction. This step is a significant advancement in our quest to solve for y. We have successfully isolated the variable and set up the equation for the final calculations. Let's proceed with confidence and tackle the next step in our algebraic adventure.
Step 3: Find a Common Denominator and Subtract the Fractions
Now that we have y = 29/4 - 5/6, we need to find a common denominator to subtract these fractions. Fractions can only be added or subtracted if they have the same denominator. The common denominator is the least common multiple (LCM) of the denominators, which in this case are 4 and 6. The LCM of 4 and 6 is 12. Understanding how to find a common denominator is a fundamental skill in arithmetic and algebra. It allows us to perform operations on fractions and simplify expressions. This step is crucial because it sets the stage for accurately subtracting the fractions and determining the value of y. The LCM ensures that we are working with the smallest possible denominator, which simplifies the calculations and reduces the likelihood of errors.
Finding the common denominator involves identifying a number that both denominators can divide into evenly. In this case, 12 is the smallest number that both 4 and 6 divide into. Once we have the common denominator, we need to convert each fraction to an equivalent fraction with the denominator of 12. This is done by multiplying both the numerator and the denominator of each fraction by the appropriate factor. This process maintains the value of the fraction while expressing it in a form that allows for subtraction. This step highlights the importance of understanding equivalent fractions and how they can be manipulated to facilitate calculations. The ability to work with fractions confidently is a key element of mathematical proficiency.
To convert 29/4 to a fraction with a denominator of 12, we multiply both the numerator and denominator by 3 (since 4 x 3 = 12). This gives us (29 x 3) / (4 x 3) = 87/12. To convert 5/6 to a fraction with a denominator of 12, we multiply both the numerator and denominator by 2 (since 6 x 2 = 12). This gives us (5 x 2) / (6 x 2) = 10/12. Now, our equation looks like this: y = 87/12 - 10/12. With the fractions now sharing a common denominator, we can proceed with the subtraction. This is a significant step forward in solving for y. We have successfully transformed the equation into a form that allows for straightforward calculation. Let's continue and complete the subtraction to reveal the value of y.
Step 4: Perform the Subtraction
With the fractions now having a common denominator, we can perform the subtraction. We have y = 87/12 - 10/12. To subtract fractions with the same denominator, we subtract the numerators and keep the denominator the same. This is a straightforward process that follows directly from the rules of fraction arithmetic. Subtracting the numerators is the key step in this process. It allows us to combine the fractions into a single fraction, which represents the difference between the two original fractions. This step is a direct application of the principles of fraction arithmetic and is essential for simplifying expressions involving fractions. Understanding and applying these principles is crucial for success in algebra and beyond.
In this case, we subtract 10 from 87, which gives us 77. The denominator remains 12. Therefore, y = 77/12. This result is an improper fraction, meaning the numerator is greater than the denominator. While this is a valid answer, it is often preferable to express the solution as a mixed number. This allows for a more intuitive understanding of the value of y. Converting an improper fraction to a mixed number involves dividing the numerator by the denominator and expressing the result as a whole number and a remainder. This process is the reverse of converting a mixed number to an improper fraction, and it is a valuable skill for simplifying and interpreting mathematical results.
So, performing the subtraction, we find that y = 77/12. We have successfully subtracted the fractions and obtained a value for y. However, our journey is not yet complete. We can further simplify this result by converting it to a mixed number. This final step will provide a clearer representation of the solution and bring us to the ultimate answer. Let's proceed with converting the improper fraction to a mixed number, completing our algebraic adventure.
Step 5: Convert the Improper Fraction to a Mixed Number (Optional but Recommended)
While y = 77/12 is a correct answer, it's often beneficial to convert the improper fraction to a mixed number. This provides a clearer sense of the magnitude of y. A mixed number combines a whole number and a proper fraction, making it easier to visualize and understand the value. Converting an improper fraction to a mixed number is a fundamental skill in arithmetic, and it is particularly useful when dealing with real-world applications. This step is optional in the sense that the solution is mathematically complete as an improper fraction, but it is highly recommended for clarity and ease of interpretation.
To convert 77/12 to a mixed number, we divide 77 by 12. The quotient becomes the whole number part of the mixed number, and the remainder becomes the numerator of the fractional part. The denominator remains the same. This process is the reverse of converting a mixed number to an improper fraction, and it is an essential skill for simplifying and interpreting mathematical results. The division process gives us a whole number and a remainder, which directly translate into the components of the mixed number. Understanding this relationship is key to mastering the conversion process. The ability to move fluently between improper fractions and mixed numbers is a valuable asset in mathematics.
Dividing 77 by 12, we get a quotient of 6 and a remainder of 5. Therefore, 77/12 is equal to 6 5/12. This means that y = 6 5/12. Now, we have expressed the solution as a mixed number, which provides a clearer understanding of its value. We have successfully converted the improper fraction and arrived at the final, simplified answer. This step completes our algebraic journey and provides a comprehensive solution to the original equation. Let's reflect on the steps we have taken and appreciate the power of algebraic manipulation in solving for unknowns.
