Frequently Asked Questions

How do you add fractions?

To add fractions, find a common denominator, convert both fractions, add the numerators, and simplify. For example: 1/2 + 1/4 = 2/4 + 1/4 = 3/4.

How do you multiply fractions?

To multiply fractions, multiply the numerators together and multiply the denominators together, then simplify. For example: 1/2 × 3/4 = 3/8.

How do you divide fractions?

To divide fractions, multiply by the reciprocal of the second fraction. For example: 1/2 ÷ 3/4 = 1/2 × 4/3 = 4/6 = 2/3.

What does it mean to simplify a fraction?

Simplifying a fraction means reducing it to its lowest terms by dividing both numerator and denominator by their greatest common divisor (GCD). For example: 6/8 simplifies to 3/4.

What is a mixed number?

A mixed number combines a whole number with a fraction. For example, 7/4 as a mixed number is 1 3/4 (one and three-fourths).
