How to Multiply Fractions
Multiplying fractions is a straightforward process. Here’s a step-by-step guide:
Step 1: Multiply the Numerators
- The numerator is the top number of a fraction.
- Multiply the numerators of the two fractions to get the numerator of the answer.
Step 2: Multiply the Denominators
- The denominator is the bottom number of a fraction.
- Multiply the denominators of the two fractions to get the denominator of the answer.
Step 3: Simplify the Fraction (if needed)
- If possible, simplify the resulting fraction by dividing both numerator and denominator by their greatest common divisor (GCD).
Example
Multiply: 23×45\frac{2}{3}\times \frac{4}{5}32×54
- Multiply numerators: 2×4=82\times 4=82×4=8
- Multiply denominators: 3×5=153\times 5=153×5=15
- Result: 815\frac{8}{15}158 (already in simplest form)
Summary Formula
ab×cd=a×cb×d\frac{a}{b}\times \frac{c}{d}=\frac{a\times c}{b\times d}ba×dc=b×da×c
