7.5 gallons.
To find out how many gallons are left in the tank at 30%, you can multiply the tank's total capacity by 0.30 (which represents 30%). For a 250 gallon tank, this would be 250 * 0.30 = 75 gallons left at 30%.

0.3 gallons.
5 percent of 30 gallons = 1.5 gallo ns = 5% of 30 gallo ns = 0.05 * 30 = 1.5 gallo ns
Answer10-30 gallons per day.
25/30 x 100 = 83.3 recurring (that is, 83.3333...) percent. Therefore, 25 is 83.3333... percent of 30.
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.
25% + 30 = 30.25
25 percent out of 120= 30 25% of 120 = 25% * 120 = 25%/100% * 120 = 0.25 * 120 = 30
25 gallons short box / 30 gallons long box
25% of 30 miles= 25% * 30= 0.25 * 30= 7.5 miles
