Question

A recipe uses 5 cups of flour for every 2 cups of sugar how much flour is needed for 1 cup of sugar

need this fast ;-; plz help

Answer 1

2.5 cups of flour

5 = 2
2 divided by 2 = 1
5 divided by 2 = 2.5

Answer 2

There are a couple of ways to look at this.

1) Set up a ratio: 2 cups sugar to 5 cups flour = 5 cups sugar to x cups flour

2/5 = 5/x

cross multiply

2x = 25

x = 12 1/2 cups flour

2) Look at the factor by which the cups of sugar was increased and increase

the cups of flour by the same factor.

2x = 5

x = 2.5

The sugar was increased by a factor of 2.5 so increase flour by same factor.

5(2.5) = 12 1/2 cups flour
