Question

The ratio of cups of sugar to cups of chocolate chips in a recipe is 2 : 4 if 36 cups of these ingredients are used, how many cups were sugar ?

Answer 1

Data:


`(sugar)/(chocolate) = (2)/(4)`
cups of these ingredients = 36

Solving:


`(S)/(2) + (C)/(4) = (36)/(6)`


`(S)/(2) = (36)/(6)`

`6*S = 2*36`

`6S = 72`

`S = (72)/(6)`

`\boxed{S = 12}`



`(C)/(4) = (36)/(6)`

`6*C = 4*36`

`6S = 144`

`C = (144)/(6)`

`\boxed{C = 24}`

So:
cups of these ingredients = 36
S+C = 12+24 = 36 (True)

How many cups were sugar ?


`\boxed{Sugar Cups = 12}`
