Question

Gina is increasing her chocolate chip cookie recipe to 1 1/2 batches. If the original recipe calls for 3 1/2 cups of flour, how much flour does she need for 1 1/2 batches?

Answer 1

To make 1 1/2 batches of chocolate chip cookies from a recipe that uses 3 1/2 cups of flour for one batch, Gina will need 5 1/4 cups of flour.

Step-by-step explanation:

Gina is increasing her chocolate chip cookie recipe to 1 1/2 batches. If the original recipe calls for 3 1/2 cups of flour, we need to calculate how much flour is needed for the increased batch size. First, convert the mixed numbers into improper fractions for easier multiplication. 1 1/2 becomes 3/2 and 3 1/2 becomes 7/2. Then, you multiply the fraction representing the batch size by the fraction representing the flour needed for one batch:

(3/2) × (7/2) = 21/4

Now, simplify the improper fraction to a mixed number to find out how much flour is needed:

21/4 = 5 1/4 cups of flour

Therefore, Gina will need 5 1/4 cups of flour for 1 1/2 batches of her chocolate chip cookies.
