Question

Benny wants to make cookies.To make cookies, he needs 7/3 cups of flour per batch of cookies.If Benny has 7 cups of flour, then how many batches of cookies can Benny make?

Answer 1

With 7 cups of flour 3.13 batches of cookies can be made.

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 cookie to flour = 1 : 2.33

Now, the amount of flour Benny has = 7 cups

Let the total batches of cookie made = m

or, ratio of cookie to flour = m : 7

So, by the RATIO OF PROPORTIONALITY:

`(1)/(2.23)  = (m)/(7 )`

⇒ 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.
