How do I add fractions?

Find a common denominator, add numerators. E.g., 1/4 + 1/2 = 1/4 + 2/4 = 3/4

How do I subtract fractions?

Find a common denominator, subtract numerators. E.g., 3/4 - 1/2 = 3/4 - 2/4 = 1/4

Multiply numerators together, multiply denominators. E.g., 2/3 × 3/4 = 6/12 = 1/2

Multiply by the reciprocal. E.g., 1/2 ÷ 3/4 = 1/2 × 4/3 = 4/6 = 2/3

Add, subtract, multiply, or divide fractions with automatic simplification.
