FAQ
How do I add two fractions?▶
Multiply the numerator of each fraction by the other denominator, add them for the new numerator, and multiply the denominators for the new denominator. Then simplify using the greatest common factor.
How do I divide fractions?▶
Flip the second fraction (reciprocal) and multiply. For example 1/2 / 3/4 = 1/2 * 4/3 = 4/6 = 2/3.
