A 2L punch recipe calls for orange and ginger ale in the ratio of 2:5
Nastasia [14]

Answer:

a) 4/7 L = 0.57 L

b) 25/7 L = 3.57 L

Step-by-step explanation:

The ratio of orange juice to ginger ale is 2:5.

Add 2 + 5 = 7.

The ratio of orange juice to ginger ale to total drink is 2:5:7.

a) The fraction of orange juice is 2/7 of the total drink.

To make 2 L, you will need 2/7 of 2 L to be orange juice.

2/7 * 2 L = 4/7 L = 0.57 L

b) The fraction of ginger ale is 5/7 of the total drink.

5/7 * 5 L = 25/7 L = 3.57 L
