To solve a proportion, you cross multiply. For example, if this was the proportion:
2/4 = 3/x, you would multiply 2 with x and 4 with 3. The products will be used in your next equation. In this case, your next equation is 2x = 12. Now you want to isolate x, so divide by two for both sides. Your answer will be x = 6.

How do you solve for missing sides in similar figures?
set up a proportion. cross multiply. solve
How can you solve problems involving percents?
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
Solve the proportion 1 over 8 equals x over 72?
x is 9.
Solve the proportion 5 over 6 equals x over 30?
5/6=x/30 150=6x 25=x
Solve the proportion 3 over 7 equals x over 63?
3/7=x/63 189=7x 27=x
How do you solve the proportion of something?
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.
How can you use a proportion to solve a percent question?

Why can you solve percent problems as a proportion problem?
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,
