Frequently Asked Questions

How do I add fractions with different denominators?

Find the least common denominator, convert each fraction, then add the numerators. Example: 1/3 + 1/4 = 4/12 + 3/12 = 7/12.

How do I multiply fractions?

Multiply numerators together and denominators together: (2/3) × (4/5) = 8/15. No common denominator needed. Simplify the result if possible.

How do I divide fractions?

Multiply by the reciprocal of the divisor: (3/4) ÷ (2/5) = (3/4) × (5/2) = 15/8. The "keep, change, flip" rule.

How do I convert an improper fraction to a mixed number?

Divide numerator by denominator. The quotient is the whole part; the remainder over the original denominator is the fraction. So 11/4 = 2 ¾.
