There cannot be a "proportion of something": proportion is a relationship between two things, and how you solve it depends on whether they (or their transformations) are in direct proportion or inverse proportion.
the three kinds of proportions are indirect proportion, direct proportion and thepartitive proportion
3x = 40

Because you simply set it up in a proportion box, for example if you have the fraction 4/8 you put the 4 on top of the 8 and 100 next to the 8 because with percents you always use 100. then solve,

A percent is simply a proportion out of 100.

Calculus.
That would depend on the specific problem. The "rule of three" (i.e., solving proportions) can help for many standard problems; i.e., you consider a proportion, where the percentage has a denominator of 100. Here are some examples:1) What's 17% of 2000? The proportion to solve is: 17/100 = x/2000 2) 500 is what percentage of 2000? The proportion to solve is: x/100 = 500/2000 3) 500 is 10% of what number? The proportion to solve is: 500/x = 10/100
set up a proportion. cross multiply. solve
nevermind, i just realized it. It's is/of=%/100
a proportion is an equation. a / b = c / d cross multiply: ad = bc then solve
