Question

Stephanie has 24 pieces of fruit. She only has apples and oranges. If the ratio of apples to oranges that Stephanie has is 3:5, how many apples does Stephanie have?

Answer 1

Answer:

apples = 9

Oranges = 15

Step-by-step explanation:

Let the apples = x

Let the oranges = y

x + y = 24

x/y = 3/5                 Cross multiply

5x = 3y                   Divide by 5

x = 3/5 y                 Substitute for x in x + y = 24

3/5 y + y = 24         Change 3/5 to a decimal

0.6 y + y = 24         Combine

1.6 y = 24                Divide by 1.6

y = 24/1.6

y = 15

x + y = 24                Substitute for y  

x + 15 = 24               Subtract 15

x = 24 - 15

x = 9
