Aminah is planning on making cookies for a class celebration. Her recipe uses 2.5 cups of sugar for every batch. She wants to make 2.25 batches of the recipe. How much sugar will Aminah need?

Question

A.
4.75 cups

B.
5.625 cups

C.
0.9 cups

D.
56.25 cups

Answer 1

To find out how much sugar Aminah will need for 2.25 batches of the recipe, we can multiply the amount of sugar needed for one batch by the number of batches.

The amount of sugar for one batch is 2.5 cups. Therefore:

\[ \text{Total sugar} = \text{Sugar per batch} \times \text{Number of batches} \] \[ \text{Total sugar} = 2.5 , \text{cups} \times 2.25 \]

Now, perform the multiplication:

\[ 2.5 \times 2.25 = 5.625 \]

So, Aminah will need 5.625 cups of sugar.

The correct answer is B. 5.625 cups.
