Addition and Subtraction of Fractions

How to add and subtract fraction numbers.

Addition

Example 1:

   2 3/4 = 2 6/8

+ 4 3/8 = 4 3/8

+ 3 1/2 = 3 4/8

            = 9 13/8 

            = 10 5/8

Example 2:

   10 7/8   = 10 14/16

+ 12 3/16 = 12 3/16

+ 9 1/4     = 9  4/16

                = 31 21/16

                = 32 5/16

Subtraction

Example 3:

   6 3/4 = 6 6/8

-  4 3/8 = 4 3/8

            = 2 3/8

Example 4:

   10 3/16 = 10 3/16 = 9 19/16

-  4 3/8    = 4 6/16   =  4 6/16

                               = 5 13/16
