Question

Keith spends 1/6 of his savings on a magazine 2/5 of the remainder on a storybook what fraction of his savings is left

Answer 1

 he spent 2/5*25=10
So he has spent 5+10=15
15/30=1/2
so he has 1/2 or $15 dollars left.

I hope it correct

Answer 2

6/6 - 1/6 = 5/6

5/6 - 2/5
= ( 25 - 12)/30

= 13/30
