Adding and Subtracting Fractions with Like Denominators

Parts of a Fraction 3 4 = the number of parts = the total number of parts that equal a whole

Parts of a Fraction 3 4 = numerator = denominator

Adding Like Denominators 1/4 3 4 1 4 4 4 + = Only add the numerators

Add these fractions 1/5 3 5 1 5 + = 4 5

Add these fractions 1/4 2 4 1 4 + = 3 4

Add these fractions 5 6 2 6 3 6 + = 1 6 1 6 1 6 1 6 1 6

4 6 2 6 2 6 + = 1 6 1 6 1 6 1 6

Add these fractions 3 12 5 + = 8

Add these fractions 3 10 1 + = 4

Add these fractions 3 9 4 9 + = 7 9 4 4

1 8 3 8 + = 4 8 5 5

Simplify Your Answer 4 8 = 4 4 1 2 ÷ 55

Add these fractions 1 9 2 9 + = 3 9 473

Simplify Your Answer 3 9 = 3 3 1 3 ÷ 77

Subtracting Like Denominators 1/4 4 4 1 4 3 4 - = Only subtract the numerators

Subtract these fractions 1/5 4 5 1 5 - = 3 5

Subtract these fractions 1/4 3 4 1 4 - = 2 4

Subtract these fractions 3 6 2 6 5 6 - = 1 6 1 6 1 6 1 6 1 6

Subtract these fractions 2 6 2 6 4 6 - = 1 6 1 6 1 6 1 6

Subtract these fractions 3 12 5 - = 2

Subtract these fractions 3 10 9 - = 6

Subtract these fractions 3 9 4 9 - = 1 9 4 4

1 8 7 8 - = 6 8 5 5

Simplify Your Answer 6 8 = 2 2 3 4 ÷ 55

Subtract these fractions 2 9 8 9 - = 6 9 413

Simplify Your Answer 6 9 = 3 3 2 3 ÷ 11
