57 is what percent of 613 - 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 613 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 613, so we can write it down as 100%=613.
4. We know, that x% equals 57 of the output value, so we can write it down as x%=57.
5. Now we have two simple equations:
1) 100%=613
2) x%=57
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%=613/57
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 57 is what percent of 613

100%/x%=613/57
(100/x)*x=(613/57)*x       - we multiply both sides of the equation by x
100=10.754385964912*x       - we divide both sides of the equation by (10.754385964912) to get x
100/10.754385964912=x
9.2985318107667=x
x=9.2985318107667

now we have:
57 is 9.2985318107667% of 613
