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.
wow
Set up a proportion equation.
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

7/n=540/6
direct proportion: y=kx inverse proportion: y=k/x
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,
No, a proportion does not have to have an unknown. A proportion is simply a statement that two ratios are equal, which can be expressed with known values. However, in many mathematical problems, proportions are used to solve for an unknown variable, making them a common tool in such cases.
when both increaes its direct proportion and when one increase and othe decreases its inverse proportion.
Yes it does rely on direct proportion.
