Tristen walked 13 1/4 hours in May and June. In May he walked 6 4/6 hours. How many hours did he walk inJune
valina [46]

Answer:

6  7/12 hours in June

Step-by-step explanation:

Find the answer to this question by subtracting 6  4/6 hours from the total 13  1/4 hours:

13  1/4 hours   is equivalent to 12  5/4 hours (we borrow '1' from 13  1/4).

Thus, we have

 12  5/4 hours              Note that the LCD of 5/4 and 4/6 is 12.  Thus

-   6  4/6 hours               we have

 12  15/12 hours

-  6    8/12 hours

--------------------------

   6    7/12 hours

Tristen walked 6  7/12 hours in June.
