Sometimes math problems include the word “of,” as in **What is 1/3 of 3/8?** Of means you should multiply so you need to solve 1/3 × 3/8. To do math with mixed numbers (whole numbers and fractions) use the Mixed Numbers Calculator.

## Math on Fractions with Unlike Denominators

There are 2 cases where you need to know if your fractions have different denominators:

if you are adding fractions if you are subtracting fractions

## How to Add or Subtract Fractions

Find the least common denominator For your first fraction, find what number you need to multiply the denominator by to result in the least common denominator Multiply the numerator and denominator of your first fraction by that number Repeat Steps 3 and 4 for each fraction For addition equations, add the fraction numerators For subtraction equations, subtract the fraction numerators Convert improper fractions to mixed numbers Reduce the fraction to lowest terms

## How to Multiply Fractions

Multiply all numerators together Multiply all denominators together Reduce the result to lowest terms

## How to Divide Fractions

Rewrite the equation as in “Keep, Change, Flip” **Keep** the first fraction **Change** the division sign to multiplication **Flip** the second fraction by switching the top and bottom numbers Multiply all numerators together Multiply all denominators together Reduce the result to lowest terms

## Fraction Formulas

There is a way to add or subtract fractions without finding the least common denominator (LCD). This method involves cross multiplication of the fractions. See the formulas below.

You may find that it is easier to use these formulas than to do the math to find the least common denominator.
