Adding Fractions with Common Units

Use common denominators to add fractions and explain why the denominator represents the unit size.

Published lesson

When fractions have the same denominator, add their numerators and keep the denominator because the parts have the same size.

For different denominators, first rewrite the fractions with a common denominator. Then add the numerators and simplify when possible.

1/4 + 2/4 = 3/4
