How to multiply fractions

Multiplying fractions is the easiest operation: multiply the numerators and multiply the denominators. 3/4 × 8/9 = (3 × 8) / (4 × 9) = 24/36, which simplifies to 2/3. You don't need a common denominator.

Mixed numbers are turned into improper fractions first: 1 1/2 × 2/3 = 3/2 × 2/3 = 6/6 = 1.
