About this worksheet
To add fractions with different denominators, students first rewrite them with a common denominator, then add the numerators. This worksheet practices that process and simplifying the sum to lowest terms.
The reference box on page 1 walks through finding the least common denominator with a worked example. Section A on page 1 gives six sums to compute and write in simplest form. Section B on page 2 has four word problems about painting, mixing, and distance.
Page 3 is a complete answer key that shows the common-denominator step for every item. The worksheet pairs well with the Adding Fractions with Like Denominators and Simplifying Fractions worksheets.
