Question

A recipe that makes 4 servings calls for 2/3 cup of flour. How much flour is required to make 20 servings? 6 cups 3/1/3 cups 2/3 cups 2/15 cups

Answer 1

20 servings / 4 servings = 5 times as much.

Multiply the amount needed for 4 servings by 5:

2/3 cups x 5 = 10/3 = 3 1/3 cups total

Answer 2

`3(1)/(3)\text{ cups}`

Explanation:

Given,

Total cups of flour required for 4 servings =
`(2)/(3)`

So, the cups required for 1 serving =
`(2)/(12)`

Thus,

The cups of flour required for 20 serving = 20 × cups required for 1 serving

`=20* (2)/(12)`

`=(40)/(12)`

`=(10)/(3)`

`=3(1)/(3)`

Hence, SECOND option is correct.
