Question

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?

Answer 1

A particular type of muffin requires 1 cup of milk and 1.5 cups of chocolates.​

Riya has 7.5 cups of chocolates.

The number of cups of milk required for 7.5 cups of chocolates $=\frac{7.5}{1.5}=5$ cups

Alternate ways

Since the number of cups of milk and chocolates is in direct proportion.

$\therefore \frac{1\text{cup of milk}}{1.5\text{cups of chocolates}}=\frac{x\text{cup of milk}}{7.5\text{cups of chocolates}}$​

$\Rightarrow x=\frac{7.5}{1.5}=5$ cups​
