57 is what percent of 554 - 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 554 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 554, so we can write it down as 100%=554.
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%=554
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%=554/57
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 554

100%/x%=554/57
(100/x)*x=(554/57)*x       - we multiply both sides of the equation by x
100=9.719298245614*x       - we divide both sides of the equation by (9.719298245614) to get x
100/9.719298245614=x
10.28880866426=x
x=10.28880866426

now we have:
57 is 10.28880866426% of 554
