A hot chocolate recipe calls for two teaspoons of cocoa for every cup of milk. How many teaspoons of cocoa are needed for a batch that uses nine cups of milk?

1 answer

To determine the number of teaspoons of cocoa needed for nine cups of milk, we can use the given ratio of cocoa to milk, which is 2 teaspoons of cocoa for every 1 cup of milk.

We calculate the amount of cocoa needed as follows:

\[ \text{Cocoa needed} = \text{Cups of milk} \times \text{Teaspoons of cocoa per cup} \]

Substituting the values:

\[ \text{Cocoa needed} = 9 \text{ cups} \times 2 \text{ teaspoons/cup} = 18 \text{ teaspoons} \]

Therefore, for nine cups of milk, you need 18 teaspoons of cocoa.
