Subtracting fractions with different denominators can be done mentally both accurately and rapidly using this cool math trick.

How to subtract fractions with whole numbers and different denominators. Steps how to add or subtract fractions with different denominators. Make sure the bottom numbers (the denominators) are the same. Make the denominator of both the fractions the same.

By subtracting the whole numbers separately and the fractions separately by making their denominators equal. Basically, we need to find a common multiple that they share. Here’s the easy way to subtract fractions that have different denominators:

The common multiples of 2 are 2, 4, 6, etc. Add the numerators and place the sum over the common denominator. How to add and subtract fractions when the denominators are the same.

For the final answer, you’ll need to simplify the fraction result if necessary. Using the example above, to replace the denominator with 6, we’re multiplying. Keep the denominator the same.

Make an improper fraction from the mixed fraction. Given two unlike fractions where the denominators are not the same. If the fractions have different denominators, first convert them to equivalent forms with the lcd.

This is a shortcut method of fraction subtraction. The way to minus fractions is. If the denominators are the unlike fractions, follow the below steps to subtract the fractions.
