Lerato

Lerato picks 400 apples from the tree in the orchard. Lerato bottles 4/10 of the apples, use 1/8 of the apple in pie, and sells 3/20 of the apples.

A, How many apples does Lerato sell?

B, How many does she bottle?

C, How many apples does she use in the pies?

D, How many apples are left for her family to eat?

Correct answer:

A =  60
B =  160
C =  50
D =  130

Step-by-step explanation:

$$\begin{gathered} n=400 \\ A=\frac{3}{20}\cdot n=\frac{3}{20}\cdot 400=\frac{3\cdot 400}{20}=\frac{1200}{20}=60 \end{gathered}$$

$B=\frac{4}{10}\cdot n=\frac{4}{10}\cdot 400=\frac{4\cdot 400}{10}=\frac{1600}{10}=160$

$C=\frac{1}{8}\cdot n=\frac{1}{8}\cdot 400=\frac{1\cdot 400}{8}=\frac{400}{8}=50$

$D=n-A-B-C=400-60-160-50=130$
