How do you divide fractions?

Back

To divide fractions, multiply the first fraction by the reciprocal of the second fraction. For example, (a/b) ÷ (c/d) = (a/b) * (d/c).

How do you add fractions with different denominators?

Back

To add fractions with different denominators, first find the least common denominator (LCD), convert the fractions, and then add the numerators.
