A certain recipe requires 2 3/5 cups of flour, and 3 1/4 cups of sugar.

a) if 3/8 of the recipe is to be made how much sugar is needed?
b) if the above ingredients are required for one batch, find the amount of flour needed for a triple batch.

1 answer

sugar 3 1/4 cups = 13/4 cups

Multiply 13/4 times 3/8

(13 x 3)/(4 x 8)

leave in simplest form. Most likely you should convert back to a mixed number.

flour triple batch means to multiply by 3

2 3/5 cups = 13/5 multiply by 3/1

39/5 = changed back to a mixed number.
