Question

18. A juice recipe calls for 3 1/2 cups

of sugar and will serve 60 people.
How much sugar would you need
if you reduced the recipe to serve
only 48 people?
A 4 2/3c B 3 1/2c C 2 4/5 c D 2 1/2c

Answer 1

C. 2
`(4)/(5)` cups

Explanation:

We want 3.5 (3 1/2) cups of sugar that serves 60 people to serve 48 people instead. So we use proportions. Set it up:

`(x)/(3.5) = (48)/(60)`

60x = 168 (48 x 3.5)

/60 /60

x = 2.8 cups of sugar serves 48 people.

Change 2.8 into fractions: 2
`(4)/(5)`
