Understanding complex fractions with rational numbers can seem difficult at first. But don’t worry! Once you learn how to do it, it becomes much easier. Here’s a simple way to simplify them:

1. Find the Complex Fraction: Start by looking at the top part (numerator) and the bottom part (denominator). A complex fraction might look like this: $\frac{\frac{a}{b}}{\frac{c}{d}}$.

2. Use the Reciprocal: To make things simpler, you can multiply by the reciprocal of the bottom part. This means you change the division into multiplication.

   So, it changes from:

   $\frac{\frac{a}{b}}{\frac{c}{d}}$

   to:

   $\frac{a}{b} \times \frac{d}{c}$

3. Multiply the Top and Bottom: Next, just multiply the top parts (numerators) together and the bottom parts (denominators) together:

   $\frac{a \cdot d}{b \cdot c}$

4. Simplify Further: Look for numbers that can be divided out from the top and bottom. If you see any common factors, simplify them.

5. Final Answer: Make sure your final answer is the simplest form. Don’t forget to double-check your work!

By practicing these steps, you’ll get the hang of complex fractions in no time!
