Question

Josie makes fruit punch by mixing fruit juice and lemonade in the ratio 1:2

She needs to make 18 litres of punch for a party.
How much of each ingredient does she need?
Fruit juice =
litres
Lemonade = litres

Answer 1

Fruit juice: 6 L

Lemonade: 12 L

Explanation:

The fraction of the punch that is fruit juice is 1/(1+2) = 1/3. The amount of fruit juice Josie will need for 18 L of punch is ...

fruit juice = (1/3)(18 L) = 6 L

The remaining 18 -6 = 12 L of liquid is lemonade.

Fruit juice: 6 L

Lemonade: 12 L
