A recipe for a particular type of muffins requires 1 cup of milk and 1.5 cups of chocolates. Riya has 7.5 cups of chocolates. If she is using the recipe as a guide, how many cups of milk will she need to prepare muffins?

Solution:

The ratio of Cups of Milk to the Cups of chocolate is 1:1.5 or 1:3/2 or 2:3

So if Riya is using 7.5 cups of chocolate and,

If the number of cups = x for 7.5 cups of chocolate then number of cups required to prepare muffin are:

x : 7.5 = 2:3

x/7.5 = 2/3

x = (2/3) × 15/2

[7.5 = 15/2]

x = 5

Hence 5 cups of milk will be required for 7.5 cups of chocolate to prepare muffins.

✦ Try This: A recipe for a particular type of muffins requires 2 cup of milk and 4 cups of chocolates. Riya has 9 cups of chocolates. If she is using the recipe as a guide, how many cups of milk will she need to prepare muffins?

The ratio of Cups of Milk to the Cups of chocolate is 2:4 or 1:2

So if Riya is using 9 cups of chocolate and,

If the number of cups = x for these 9 cups of chocolate then number of cups required to prepare muffin are:

x : 9 = 1:2

x/9 = 1/2

x = 9/2

x = 4.5

Hence 4.5 cups of milk will be required for 9.0 cups of chocolate to prepare muffins.
