513.6 is what percent of 790 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 790 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 790, so we can write it down as 100%=790.
4. We know, that x% equals 513.6 of the output value, so we can write it down as x%=513.6.
5. Now we have two simple equations:
1) 100%=790
2) x%=513.6
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=790/513.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 513.6 is what percent of 790

100%/x%=790/513.6
(100/x)*x=(790/513.6)*x       - we multiply both sides of the equation by x
100=1.5381619937695*x       - we divide both sides of the equation by (1.5381619937695) to get x
100/1.5381619937695=x
65.012658227848=x
x=65.012658227848

now we have:
513.6 is 65.012658227848% of 790
