# Addition and Subtraction of Fractions

## How to add and subtract fraction numbers.

Example 1:

2 3/4 = 2 6/8

+ 4 3/8 = 4 3/8

+ 3 1/2 = 3 4/8

=            9 12/8

=            10 5/8

Example 2:

10 7/8   = 10 14/16

+ 12 3/16 = 12 2/16

+ 9 1/4     = 9 4/16

=                31 19/16

=                32 3/16

### 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
