Let's get started and have a blast learning!

First things first, what does the equation actually mean? We're looking for a value for θ{\theta} (theta, the Greek letter) that makes the equation true. It's like a puzzle where we have to find the missing piece. The equation involves a mixed number and a repeating decimal, so our initial steps will be to convert them into forms that are easier to work with. Remember, the goal is always to isolate θ{\theta} on one side of the equation, which means we need to get rid of everything else that's hanging out with it. We'll use some basic algebraic principles, like inverse operations, to achieve this. This means doing the opposite of whatever is being done to θ{\theta}. For example, if it's being multiplied, we'll divide. If it's being added, we'll subtract. By carefully applying these rules, we can unravel the equation and find the value of θ{\theta}. The key here is patience and precision. Take your time, double-check your work, and you'll be golden. This whole process is about finding the value of an unknown variable, and it's a super useful skill in all sorts of math problems and real-life situations. So, let’s transform the equation into a more manageable format to crack this math problem. It’s like preparing the ingredients before you start cooking! By the end, you'll be equipped to tackle similar problems with confidence.

Converting Mixed Numbers and Repeating Decimals

Alright, let's start by converting 3123 \frac{1}{2} to an improper fraction. This makes it easier to multiply. Remember, to do this, multiply the whole number (3) by the denominator (2) and add the numerator (1). Then, place this over the original denominator. So, 3123 \frac{1}{2} becomes (3×2)+12=72\frac{(3 \times 2) + 1}{2} = \frac{7}{2}. Easy peasy, right? Now, let's convert the repeating decimal 310‾3 \overline{10}. The notation 310‾3 \overline{10} means 3.101010… where the digits '10' repeat infinitely. To convert this into a fraction, we can use a clever trick: Let x = 3.101010… Now, since the repeating part has two digits (10), we multiply x by 100: 100x = 310.101010… Subtracting the original equation from this one, we get 99x = 307. This simplifies to x=30799x = \frac{307}{99}.

So, now we have the equation: 72×θ=30799\frac{7}{2} \times \theta = \frac{307}{99}. See? Much cleaner already!

This conversion is a fundamental step because it allows us to work with fractions, which are generally easier to handle when solving equations. Dealing with repeating decimals directly can get messy, so converting to fractions simplifies the math and reduces the chances of errors. It's like changing the units of measurement to make the calculations simpler. Furthermore, understanding how to convert between mixed numbers, improper fractions, and repeating decimals is a core skill in mathematics. This knowledge will be super helpful for you in future math challenges! It will also make you feel like a mathematical superhero, ready to take on any equation that comes your way. Mastering these conversions will allow you to work with different forms of numbers, ensuring you can tackle all types of mathematical problems. It's like having a universal translator for numbers, making everything easier to understand and manipulate. This is a very useful skill for many other types of mathematical problems.

Isolating θ: The Key to Solving

Now comes the fun part: isolating θ{\theta}! Our equation is currently 72×θ=30799\frac{7}{2} \times \theta = \frac{307}{99}. To isolate θ{\theta}, we need to get rid of the 72\frac{7}{2} that's multiplying it. The inverse operation of multiplication is division, so we're going to divide both sides of the equation by 72\frac{7}{2}. Remember, whatever you do to one side of the equation, you MUST do to the other side to keep it balanced. When we divide by a fraction, it's the same as multiplying by its reciprocal. The reciprocal of 72\frac{7}{2} is 27\frac{2}{7}. So, we multiply both sides of the equation by 27\frac{2}{7}. This gives us:

θ=30799×27\theta = \frac{307}{99} \times \frac{2}{7}

Now, multiply the numerators together and the denominators together: θ=307×299×7=614693\theta = \frac{307 \times 2}{99 \times 7} = \frac{614}{693}.

And there you have it! We've found the value of θ{\theta}. But wait, can we simplify this fraction? Let's check. The greatest common divisor (GCD) of 614 and 693 is 1, so the fraction is already in its simplest form. This means that θ=614693\theta = \frac{614}{693}.

Isolating θ{\theta} is the heart of solving any equation. It's like peeling an onion; you're removing all the layers (coefficients and constants) until you reach the core (the variable). This process uses the fundamental properties of equality: what you do to one side, you must do to the other. This ensures that the equation remains balanced, and the solution stays valid. The use of inverse operations is critical here. These operations are like mathematical undo buttons. They allow us to reverse the effects of addition, subtraction, multiplication, and division, ultimately revealing the value of the unknown variable. Another crucial element is knowing how to handle fractions effectively, including multiplication, division, and simplification. Being able to multiply and divide fractions is essential to performing the necessary operations to solve for θ{\theta}. Furthermore, simplifying the final fraction is a key step. Reducing fractions to their lowest terms provides the clearest and most concise representation of the solution. This process not only makes the answer look neat but also reduces the chance of further errors in future calculations. Remember, practicing these steps will build your confidence and make you a pro at isolating variables in any equation.

Checking Your Work and Final Thoughts

Great job, guys! We've solved for θ{\theta}. But is our answer right? It's always a good idea to check your work. Let's substitute 614693{\frac{614}{693}} back into the original equation: 312×614693=310‾3 \frac{1}{2} \times \frac{614}{693} = 3 \overline{10}. Convert everything back to their original forms: 72×614693=30799\frac{7}{2} \times \frac{614}{693} = \frac{307}{99}. Simplify the left side of the equation, you should get 42981386\frac{4298}{1386}. Then divide both the numerator and denominator by 14 and you’ll get 30799\frac{307}{99}. Voila! It checks out.

In conclusion, we successfully solved for θ{\theta} in the equation. This process involved converting mixed numbers and repeating decimals into fractions, isolating θ{\theta}, and simplifying the result. Remember, practice makes perfect.
