# Fraction Calculator

Please enter the numerator and denominator of fractions, select operation and click calculate button.

 + - * /

Select + operator and press calculate to add fractions. Math formula for adding fractions is:

$\frac{A}{B}+\frac{C}{D}=\frac{\left(AD+BC\right)}{BD}$ Example

$\frac{1}{3} + \frac{2}{5} = \frac{1\times5 + 3\times2}{3\times5} = \frac{5+6}{15} = \frac{11}{15}$

## Subtracting Fractions

Select the minus sign (+) operator and press calculate to subtract fractions. Math formula for subtracting fractions is:

$\frac{A}{B}-\frac{C}{D}=\frac{\left(AD-BC\right)}{BD}$ Example

$\frac{2}{3} - \frac{1}{5} = \frac{2\times5 - 3\times1}{3\times5} = \frac{10-3}{15} = \frac{7}{15}$

## Multiplying Fractions

Select the multiply sign (*) operator and press calculate to multiply fractions. Math formula for multiplying fractions is:

$\frac{A}{B}×\frac{C}{D}=\frac{AC}{BD}$ Example

$\frac{1}{3} \times \frac{2}{5} = \frac{1\times2}{3\times5} = \frac{2}{15}$

## Dividing Fractions

Select the division sign (/) operator and press calculate to divide fractions. Math formula for dividing fractions is:

$\frac{A}{B}÷\frac{C}{D}=\frac{AD}{BC}$ Example

$\frac{1}{3} ÷ \frac{2}{5} = \frac{1\times5}{3\times2} = \frac{5}{6}$
