Adding Fractions When One Denominator Changes Worksheet Download
This math worksheet practices adding and subtracting fractions with unlike denominators when one denominator is a multiple of the other, like 1/2 + 3/8. Students rename one fraction (1/2 = 4/8), copy the other, and add or subtract the numerators. The renamed fraction is written as a blank over its new denominator, so the step is shown on every problem.
