Understanding the Concept of Dividing Fractions

Dividing fractions is a fundamental concept in mathematics that can seem daunting at first, but with a clear understanding of the concept and a step-by-step approach, it becomes a manageable task. In this article, we will delve into the world of dividing fractions and provide a comprehensive guide on how to calculate $\frac{3}{4} \div \frac{2}{3}$.

What is Dividing Fractions?

Dividing fractions is the process of dividing one fraction by another. It involves inverting the second fraction (i.e., flipping the numerator and denominator) and then multiplying the two fractions together. This process is also known as "inverting and multiplying."

Why Do We Invert and Multiply?

When we divide one fraction by another, we are essentially asking how many times the first fraction fits into the second fraction. To determine this, we need to find the reciprocal of the second fraction (i.e., the inverse of the fraction) and then multiply it by the first fraction. This process is equivalent to multiplying the first fraction by the reciprocal of the second fraction.

How to Divide Fractions: A Step-by-Step Guide

To divide fractions, follow these simple steps:

1. Invert the second fraction: Flip the numerator and denominator of the second fraction.
2. Multiply the fractions: Multiply the first fraction by the inverted second fraction.
3. Simplify the result: Simplify the resulting fraction, if possible.

Calculating $\frac{3}{4} \div \frac{2}{3}$

Now that we have a clear understanding of the concept of dividing fractions, let's apply it to the given problem: $\frac{3}{4} \div \frac{2}{3}$.

Step 1: Invert the Second Fraction

To invert the second fraction, we need to flip the numerator and denominator. The second fraction is $\frac{2}{3}$, so its reciprocal is $\frac{3}{2}$.

Step 2: Multiply the Fractions

Now that we have the inverted second fraction, we can multiply it by the first fraction: $\frac{3}{4} \times \frac{3}{2}$.

Step 3: Simplify the Result

To simplify the resulting fraction, we need to multiply the numerators and denominators together: $\frac{3 \times 3}{4 \times 2} = \frac{9}{8}$.

Conclusion

Dividing fractions may seem like a complex concept at first, but with a clear understanding of the concept and a step-by-step approach, it becomes a manageable task. By inverting the second fraction and multiplying the two fractions together, we can calculate $\frac{3}{4} \div \frac{2}{3}$ and arrive at the final answer: $\frac{9}{8}$.
