Question

Lee earned some money from a summer job he saved 1/4 of the money and spent 1/3 of the rest on a t-shirt he then spent the remaining money on some CDs what fraction of the money was spent on CDs show your work

Answer 1

They need to be like terms (so change the denominators into things that match)
1 x3 = 3
4 x3 = 12

1 x4 = 4
3 x4 = 12

4/12 + 3/12 = 7/12 

So, 7/12 of the money was spent.

Answer 2

7/12........ I hope this is right and hope this will help you :)
