Question

A paint mixture contains 9 gallons of base for every gallon of color. In 230 gallons of paint, how many gallons of color are there?

Answer 1

base : color.....9:1...added = 10

9/10(230) = 2070/10 = 207 gallons of base
1/10(230) = 230/10 = 23 gallons of color <==

Answer 2

Hello!

9 gallons for every 1 gallon of color in ration is:

9:1
9 + 1 = 10

9 ÷ 10(230)
2,070 ÷ 10
207 gallons of base 

1 ÷ 10(230) 
230 ÷ 10
23 gallons of color 

So there are 23 gallons of color in 230 gallons of paint.

Hope I helped! (:
