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.

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
x is 9.
5/6=x/30 150=6x 25=x
3/7=x/63 189=7x 27=x
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.
A percent is simply a proportion out of 100.

The easiest way to solve a proportion is by cross-multiplying. This means you multiply the numerator of one fraction by the denominator of the other fraction and set the two products equal to each other. For example, in the proportion ( \frac{a}{b} = \frac{c}{d} ), you would calculate ( a \times d = b \times c ). Then, you can solve for the unknown variable by isolating it in the resulting equation.
