One way to change a percent into a fraction is to take the percent number and but the denominator as 100. For example if the percent number was 43 then that would be your numerator and 100 would be your denominator so it should be 43/100. Percent means out of 100 so your denominator should be 100 unless you simplify your fraction.

12 percent means 12 out of 100. You could write it as 12/100. You should reduce this though to 3/25.

In mathematics, a percentage is a way of expressing a number as a fraction of 100. Per cent meaning "per hundred". It is often denoted using the percent sign, "%". For example, 45 % (read as "forty-five percent") is equal to 45 / 100, or 0.45. Percentages are used to express how large one quantity is relative to another quantity. The first quantity usually represents a part of, or a change in, the second quantity, which should be greater than zero. For example, an increase of $ 0.15 on a price of $ 2.50 is an increase by a fraction of 0.15 / 2.50 = 0.06. Expressed as a percentage, this is therefore a 6 percent increase.

The question is best solved using basic algebra. You need 20 gallons of 32% alcohol. This will contain 0.32*20 = 6.4 gallons of pure alcohol. Now suppose you have X gallons of 25% alcohol in the mixture. That contains 0.25X gallons of pure alcohol. Also, since you have 20 gallons in total, you must have 20-X gallons of the 35% alcohol. This will contain 0.35*(20-X) = 7 - 0.35X gallons of pure alcohol. Then, the total amount of pure alcohol is 0.25X + 7 - 0.35X = 7 - 0.1X gallons. So you have 7 - 0.1X = 6.4 or 0.6 = 0.1X or X = 6. So the answer is 6 gallons of 25% alcohol and 14 gallons of the stronger stuff!

You should divide the top of the fraction by the bottom, multiply by 100 and add a "%" sign. I'm pretty sure this is what u do
