Multiply the initial number by the numerator. 30 x 3 = 90 Then divide by the denominator. 90 / 5 = 18 18 gallons.
30 gallons of volume = 4.01 cubic feet (rounded) = 0.1485cubic yard of volume (rounded)No matter what's in it.Even if it's empty.

I take it that there should be percentage signs in this question. How many gallons of pure water must be added to 10 gallons of 30% saltwater to make a solution that is 25% saltwater?" If 30% of the 10 gallons is saltwater that means that 3 gallons are saltwater. As only pure water will be added, we need to find out how many gallons = 100% if 3 gallons = 25%. The relationship of 100 to 25 is 4 : 1, so there will need to be a total of (3 x 4) gallons at the end of the operation. As 3 x 4 = 12, and as we started with 10 gallons, that means that we need to add 2 gallons of pure water.
