Question

6) When Alysha got paid she spent 1/4 of her money on rent

She spent 2/5 on other bills and put the rest in the bank.
What fraction of her pay went
into the bank?
A) 3/4
B) 3 /5
C)13/20
D) 7/20​

Answer 1

D) 7/20

Explanation:

Part of money spent = (1/4) + (2/5)

`=(1*5)/(4*5)+(2*4)/(5*4)\\\\=(5)/(20)+(8)/(20)\\\\=(13)/(20)\\`

Fraction part that went to bank = 1 - (13/20)

`=(20)/(20)-(13)/(20)\\\\=(7)/(20)`
