How do I multiply fractions?

Multiply numerators together and denominators together, then simplify. Example: 2/3 × 3/4 = (2×3)/(3×4) = 6/12 = 1/2. Multiplying fractions is generally easier than adding them.

How do I divide fractions?

Multiply the first fraction by the reciprocal of the second. Example: 2/3 ÷ 4/5 = 2/3 × 5/4 = 10/12 = 5/6. The rule is 'keep, change, flip' — keep the first fraction, change ÷ to ×, flip the second fraction.

What is a simplified fraction?

A fraction is simplified (or in lowest terms) when the numerator and denominator share no common factors other than 1. To simplify, divide both by their Greatest Common Divisor (GCD). Example: 6/8 simplified = 3/4.

What is an improper fraction?

An improper fraction has a numerator larger than its denominator (e.g., 7/4). It can be converted to a mixed number: 7/4 = 1 and 3/4. Both forms are correct, but mixed numbers are sometimes easier to interpret.
