Question

A recipe calls for 2/3 of a cup of milk for 11 cookies. How many cups of milk are needed to make 99 cookies?

Answer 1

6 cup of milk

Explanation:

From question

for 11 cookies →
`(2)/(3)` of a cup of milk required

Now,

for 99 cookies

we multiply both sides by 9.

11 × 9 =
`(2)/(3)` × 9

for 99 cookies = 6 cup of milk
