How To Subtract Fractions, Common Denominators, Different Denominators

Learn How To Subtract Fractions With Common Denominators Or Different Denominators

\frac{7}{9} - \frac{1}{9} =

The Denominators Of Both Fractions Are The Same - Subtract Numerators (7 - 1)

\frac{(7 - 1)}{9} = \frac{6}{9}

Simplify Answer Using Greatest Common Divisor

\frac{6}{9} = \frac{6 ÷ 3}{9 ÷ 3} = \frac{2}{3}

\frac{7}{4} - \frac{5}{6} =

We Must Cross-Multiply Both Fractions To Get A Common Denominator

\frac{7}{4} = \frac{7 × 6}{4 × 6} = \frac{42}{24}

\frac{5}{6} = \frac{5 × 4}{6 × 4} = \frac{20}{24}

The Denominators Of Both Fractions Are The Same - Subtract Numerators (42 - 20)

\frac{42}{24} - \frac{20}{24} = \frac{22}{24}

Simplify Answer Using Greatest Common Divisor

\frac{22}{24} = \frac{22 ÷ 2}{24 ÷ 2} = \frac{11}{12}
