      Adding Like Fractions

      Steps to find the sum of two or more like fractions:

      Step 1 Find the new numerator by adding the numerators of the given fractions.

      Step 2 Retain the (common) denominator.

      Step 3 Write the new numerator over the denominator.

      Step 4 Simplify the fraction if required.

       

      Example: Add 2/5 and 1/5

        


      Example 1: Solve 3/18 + 5/18

      Subtracting Like Fractions

      Steps to find the difference of two or more like fractions:

      Step 1 Find the new numerator by subtracting the smaller numerator from the bigger numerator.

      Step 2 Retain the (common) denominator.

      Step 3 Write the new numerator over the denominator.

      Step 4 Simplify the fraction if required.

       

      Example: Subtract 3/8 from 7/8.

       


      Example 4: Find the difference between 15/21 and 11/21.

       

       

      Example 5: Fill in the missing fractions.



       

      Example 6: Fill in the missing fractions.
