What’s the difference between 126 1/4 and 78 2/3

47  7/12

Step-by-step explanation:

Here we have two mixed numbers and need to find the difference between them.  In other words, subtract 78 2/3 from 126 1/4.

The LCD is (3)(4), or 12.  Thus we have:

126 3/12

-78  8/12

Borrow 1 (or 12/12) from 126.  We get:

125  15/12, from which it is easily possible to subtract 78  8/12:

125  15/12

- 78   8/12

  47  7/12
