Question

A recipe calls for 1 1/4 cups of sugar for every 3 cups of flour. How much sugar would be needed for 5 cups of flour?

Answer 1

`2(1)/(12)` cups of sugar required for 5 cups of flour

Explanation:

Number of cups of sugar required for 3 cups of flour =
`1 (1)/(4)`

Number of cups of sugar required for 3 cups of flour =
`(5)/(4)`

Number of cups of sugar required for 1 cup of flour
`=((5)/(4))/(3)`

Number of cups of sugar required for 5 cups of flour =
`((5)/(4))/(3) * 5`

Number of cups of sugar required for 5 cups of flour =
`(25)/(12)`

Number of cups of sugar required for 5 cups of flour =
`2(1)/(12)`

Hence
`2(1)/(12)` cups of sugar required for 5 cups of flour
