Question

A recipe calls for a total of 3 2/3 cups flour and sugar. If the recipe calls for 1/4 cup of sugar, how much flour is needed?

Answer 1

To find out how much flour is needed, you take 3 2/3 cups (of flour and sugar) - 1/4 cup (sugar) = (flour).

3 2/3 = 3 8/12
- 1/4 = 3/12
__________________ ...... That equals 3 5/12 cups of flour.

Answer 2

The amount of needed flour is
`3(5)/(12)` cups.

Explanation:

It is given that recipe calls for a total of
`3(2)/(3)` cups flour and sugar. The recipe calls for 1/4 cup of sugar.

`3(2)/(3)=(9+2)/(3)=(11)/(3)`

`recipe=flour+sugar`

`(11)/(3)=flour+(1)/(4)`

Subtract 1/4 from both the sides.

`(11)/(3)-(1)/(4)=flour+(1)/(4)-(1)/(4)`

`(44-3)/(12)=flour`

`(41)/(12)=flour`

`3(5)/(12)=flour`

Therefore, the amount of needed flour is
`3(5)/(12)` cups.
