Hope this helped!!!

Answer 2

`{\huge\red{\fbox{{࿐αɴѕωєя࿐}}}}`

Recipe A:

Cups of flour used = 3

Rolls made = 12

Cups of flour per roll

`= (3)/(12) \\ = (1)/(4) \\ = 0.25`

Recipe B:

Cups of flour used = 5

Rolls made = 24

Cups of flour per roll

`(5)/(24) \\ = 0.20`

Recipe C:

Cups of flour used = 11

Rolls made = 48

Cups of flour per roll

`(11)/(48) \\ = 0.22`

Now compare Recipe A, B & C.

`0.25 > 0.22 > 0.20`

Recipe A > Recipe C > Recipe B.

✏ So, Recipe A used the most cups of flour per roll (option a).
