Let’s solve each fraction multiplication problem step by step.
When you multiply two fractions, you:
1. Multiply the top numbers (numerators) together.
2. Multiply the bottom numbers (denominators) together.
3. Write the new fraction with the multiplied numerator on top and denominator on bottom.
4. If needed, simplify — but in these problems, all answers are already in simplest form since we’re multiplying 1 over something.
