When we're asked "what percentage of" a number, we start with the assumption that the result will be only part of that number (it could certainly be the other way, but usually not). So, remembering that a percentage is actually a fraction, we want to format the two numbers as a fraction with the smaller on top and the larger on the bottom. This gives us 32/80. The greatest common factor here is 16, which reduces the fraction to 2/5, which is equivalent to 40%. However, it's even easier to just use 8 as a GCF, because that gives you 4/10, which is easily seen to be .40 or 40%. The real key to getting this right is understanding which number is to be taken a percentage of. That will allow you to handle improper fractions the same way.

10% of 80 is 8, and 4 times 8 is 32, so the answer is 40%.
