Answer:
With 7 cups of flour 3.13 batches of cookies can be made.
Step-by-step explanation:
The amount of flour needed per batch of cookies = 7/3 cups
= 2.33 cup
⇒ 1 batch of cookies = 2.33 cup of flour
or the ratio of <u>cookie to flour = 1 : 2.33</u>
<u />
Now, the amount of flour Benny has = 7 cups
Let the total batches of cookie made = m
or, ratio of <u>cookie to flour = m : 7</u>
So, by the RATIO OF PROPORTIONALITY:
⇒ m = 7 /2.23
or, m = 3.13
or, total batches of cookie made = 3.13
Hence, from 7 cups of flour 3.13 batches of cookies can be made.
