A baker has 15 cups of flour. He sets aside 4 cups, and uses the rest for a cookie recipe that calls for 1/2 cup of flour. How many batches of cookies can the baker make?

22 batches of cookies

Step-by-step explanation:

so you have 15 cups of flour, you then take away 4 cups to get 11 left over. since the recipe wants 1/2 of a cup for 1 batch, then you would just do 11 times 2 because you need only a half for the batch. since he is making multiple batches then you count by halves to get to 11. for example ... 1/2, 1, 1/2, 2 ... and so on.

So, 22 batches of cookies can the baker make.

Step-by-step explanation:

A baker has 15 cups of flour.

He sets aside 4 cups.

So, the remaining cups = 15 - 4 = 11

A cookie recipe that calls for 1/2 cup of flour.

So, x batches of cookies can the baker make with 11 cups

Use the ratio and proportional

1 : 1/2 = x : 11 ⇒ multiply both sides by 2

2 : 1 = 2x : 22

solve for x

2x = 2 * 22

x = 22

So, 22 batches of cookies can the baker make.
