Question

Kaylee spent 4 1/4 hours on homework yesterday while Abby spent 2 1/6 on homework. How much time did Kaylee spend on homework than Abby?

Answer 1

Kaylee spent 11/12 hours studying longer than Abby.

Explanation:

First, make the denominators the same (meaning we multiply):

4 1/4 = 5/4*3 = 15/12

2 1/6 = 13/6*2 = 26/12

Then, we subtract:

26/12 - 15/12 = 11/12
