Think about the wording of the fraction.

For example: what is 60 as a percentage of 340

If you think that a fraction means something "out of" something else then you have 60 "out of" 340 which is where the 60/340 comes from.

When you type this into the calculator, you have a decimal answer. To convert a decimal into a percentage, you always x by 100 because a whole is 100%.

eg: what is 60 as a percentage of 340.

60/340 x100 = 17.647 I believe is the correct way, but I want to do it by pen and paper and see what I'm doing.
