Question

Juanita spent 3/4 of her allowance at the mall. Of the money spent at the mall, 1/2 was spent on new earphones. What part of her allowance did Juanita spend on earphones?

Answer 1

`(3)/(4) * (1)/(2) = (3)/(8)` of her allowance

Answer 2

Let

x--------> Juanita's allowance

we know that

1) Juanita spent
`3/4` of her allowance at the mall

so

Juanita spent at the mall -------->
`(3)/(4)x`

2) Of the money spent at the mall,
`1/2` was spent on new earphones

so

Juanita spent on new earphones ------->
`(3)/(4)x*(1/2)=(3)/(8)x`

therefore

the answer is

Juanita spend on earphones
`(3)/(8)` of her allowance
