Nadine spent 2/7 of her money on clothes and 1/4 on shoes.
what fraction has she have left
:
let x = fraction she has left
Assume her original total is 1
2%2F7 + 1%2F4 + x = 1
Common denominator is 28
8%2F28 + 7%2F28 + x = 1
Change 1 to 28/28
15%2F28 + x = 28%2F28
x = 28%2F28+-+15%2F28
x = 13%2F28 is the fraction she has left
