How do you multiply fractions?
Multiply numerators together and denominators together, then simplify. Example: 2/3 × 3/4 = 6/12 = 1/2.
How do you divide fractions?
Multiply by the reciprocal of the second fraction. Example: 2/3 ÷ 4/5 = 2/3 × 5/4 = 10/12 = 5/6.
How do you simplify a fraction?
Divide numerator and denominator by their GCD. Example: 12/18 → GCD = 6 → 12÷6 / 18÷6 = 2/3.
