Question

Stacy Is making 2 and 1/4 batches of cookies. If each batch calls for 1/3 of a cup of sugar, how much sugar will Stacy use?

Answer 1

Since each batch of cookies will need 1/3 cup, Stacy would need 1/3 cup for the first batch , another 1/3 cup for the second batch, and 1/4 of 1/3 cup for the 1/4 batch.

This total can be determined by multiplying 2 and 1/4 (or 9/4) by 1/3:

9/4 * 1/3 = 9/12 or 3/4 cup sugar for all the batches
