Question

Emily spends $28 on food. This amount of 4/9 of her allowance, what is Emily’s allowance?

Answer 1

Answer:

$63

Step-by-step explanation:

so we want to find 9/9 of her allowance, which is 100%

we could use a proportion:

let 'a' = full allowance

$\frac{28}{1}$ ÷ $\frac{4}{9}$ = $\frac{a}{1}$ ÷ $\frac{9}{9}$

when we divide fractions we multiply by the reciprocal to get:

28 x 9/4 = a

a = 252/4

a = 63
