Rosa bought a bag of apples. After she baked pies, she had 2/3 of a bag left. Then she gave her cousin 3/4 of these, which was 9

Masteriza [31]

Answer:

54 apples

Step-by-step explanation:

Let's say that a bag of apples has x amount of apples. Rosa has 2/3 x after baking pies then give her cousin 3/4 of them. The number of apples that Rosa have will be:

$\frac{2x}{3}$ - ( $\frac{3}{4}$ * $\frac{2x}{3}$ )=

$\frac{2x}{3}$ - $\frac{6x}{12}$ =

$\frac{8x}{12}$ - $\frac{6x}{12}$ = $\frac{2x}{12}$ = $\frac{x}{6}$

If Rosa has 9 apples, then x will be:

9 apples = $\frac{x}{6}$

x= 9 apples * 6= 54 apples
