Step 1: Convert Mixed Numbers to Improper Fractions

Alright guys, the first thing we need to do when dividing mixed numbers is to convert them into improper fractions. Remember, an improper fraction is a fraction where the numerator (the top number) is greater than or equal to the denominator (the bottom number). This is a crucial first step, as it simplifies the division process significantly. So, how do we transform our mixed numbers, 5 rac{1}{7} and 2 rac{2}{5}, into improper fractions? Let's take a look. For 5 rac{1}{7}, we multiply the whole number (5) by the denominator (7), and then add the numerator (1). This gives us: $(5 imes 7) + 1 = 36$. We keep the same denominator, 7. Therefore, 5 rac{1}{7} becomes rac{36}{7}. Now, let's do the same for 2 rac{2}{5}. We multiply the whole number (2) by the denominator (5), and then add the numerator (2). This gives us: $(2 imes 5) + 2 = 12$. We keep the same denominator, 5. Hence, 2 rac{2}{5} transforms into rac{12}{5}. So, our problem now looks like: rac{36}{7} ext{ divided by } rac{12}{5}. It's all about converting those mixed numbers into a format that's easier to work with. It's like changing the ingredients to a recipe! This conversion makes the subsequent steps much more straightforward.

Now, you might be wondering why we go through this conversion process. Well, converting mixed numbers into improper fractions lays the groundwork for seamless division. This transformation ensures that we are working with fractions in a consistent format, which simplifies the mathematical operations. Working with improper fractions eliminates the need to handle whole numbers separately, reducing the chances of making errors. This approach facilitates a streamlined and organized process, making the entire division operation more manageable. This also sets the stage for the next crucial step: understanding reciprocals. By converting to improper fractions, we are setting the stage for the next step, which involves using reciprocals. By converting the numbers into improper fractions, you're preparing them for division. This ensures that all parts of the numbers are correctly involved in the calculation, which is key to an accurate answer. Doing this conversion correctly is a fundamental skill that will help you tackle more complicated problems down the line.

Step 2: Understand and Apply the Reciprocal

Okay, team, here comes the fun part: using the reciprocal. When dividing fractions, we don't actually divide directly. Instead, we multiply by the reciprocal of the second fraction (the divisor). The reciprocal of a fraction is simply flipping the numerator and the denominator. For example, the reciprocal of rac{12}{5} is rac{5}{12}. Remember, the divisor is the number you're dividing by. So, our new problem becomes: rac{36}{7} imes rac{5}{12}. See how the division has turned into multiplication? That's the power of the reciprocal! The reciprocal is your secret weapon when dividing fractions! It's like a mathematical magic trick that simplifies the process. Finding the reciprocal involves simply switching the positions of the numerator and the denominator of the fraction you're dividing by. This switch is the key to converting division problems into multiplication problems. It transforms the problem into a format that is much more manageable and easier to solve.

So, what's the logic behind the reciprocal? Well, it's rooted in the fundamental properties of division and multiplication. Using the reciprocal is essentially equivalent to multiplying by the inverse of the divisor. By multiplying by the inverse, we maintain the mathematical equivalence and ensure that the calculation yields the correct answer. The reciprocal helps us perform division operations by reframing them as multiplication problems. Multiplying by the reciprocal effectively reverses the division process, allowing us to maintain accuracy throughout the calculation. The reciprocal is not just a procedural step; it’s a foundational concept that bridges division and multiplication, allowing you to manipulate fractions in a way that is both efficient and mathematically sound. Understanding the role of the reciprocal is crucial for mastering division problems, as it underpins the transformation of division into multiplication. Mastering the concept of reciprocals is like learning a secret code that unlocks the ability to manipulate fractions with ease and confidence. It's a foundational skill that will help you tackle more complex math problems. By grasping this concept, you can navigate division with confidence, knowing that you're applying a proven method that guarantees accurate results.

Step 3: Multiply the Fractions

Alright, now that we've got our problem set up as multiplication, let's go ahead and multiply the fractions: rac{36}{7} imes rac{5}{12}. To multiply fractions, we multiply the numerators together and the denominators together. So, we get: $(36 imes 5) / (7 imes 12) = 180 / 84$. That wasn't too hard, was it? We've successfully multiplied our fractions, and now we have a new fraction: rac{180}{84}. But wait, this fraction can be simplified! It's all about multiplying the numerators and denominators to get your answer! When we multiply the fractions, we're combining the numerators and denominators to find the new fraction. This step is about performing the arithmetic operation accurately. Remember to multiply the numerators together and the denominators together. This gives us a new fraction that needs to be simplified. Ensure that the multiplication is done correctly, as this is a crucial step towards finding the answer.

This simple step involves straightforward multiplication, ensuring that all parts of the fractions are combined. It’s also crucial to remember the rules of multiplication, making sure you multiply the numerators together and denominators together. This step is about combining the parts of the fractions in a way that is mathematically correct. This prepares the fraction for simplification in the next step. Multiplying the fractions accurately ensures you get the right result. This step combines the numerators and denominators to give you a single fraction. Remember, you have to multiply the numerators and denominators. It's all about making sure that you accurately combine the parts of the fraction. The key here is to accurately multiply the numerators and denominators. By ensuring the multiplication is correct, you are one step closer to solving the problem. Keep in mind that multiplying fractions is a fundamental skill.

Step 4: Simplify the Fraction to Its Simplest Form

Here’s where we make the fraction as simple as possible. To simplify the fraction rac{180}{84}, we need to find the greatest common divisor (GCD) of the numerator and the denominator. The GCD is the largest number that divides both numbers evenly. In this case, the GCD of 180 and 84 is 12. So, we divide both the numerator and the denominator by 12: $180 ext{ divided by } 12 = 15$, and $84 ext{ divided by } 12 = 7$. This gives us the simplified fraction rac{15}{7}. But we're not done yet! Since this is an improper fraction (the numerator is larger than the denominator), we need to convert it back into a mixed number. Simplifying fractions is like tidying up your answer – it makes it neat and easy to understand! Always simplify the fraction to make sure the answer is as simple as possible. Simplification involves dividing both the numerator and the denominator by their greatest common divisor (GCD). This process is vital as it gives the final answer in its most concise and understandable form. Remember to divide both the numerator and the denominator by the same number to maintain the value of the fraction. Simplification helps make the answers more easily understood. Simplifying fractions helps you get the most straightforward answer possible. Keep in mind that simplifying a fraction makes it easier to work with and helps avoid any unnecessary complications.

To simplify the fraction, you can find the greatest common divisor and divide both the numerator and denominator by that number. This simplifies the fraction without changing its value. It makes the answer more understandable. By simplifying the fraction, you’re making it more easily understandable.
