57.42 is what percent of 198 - 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 198 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 198, so we can write it down as 100%=198.
4. We know, that x% equals 57.42 of the output value, so we can write it down as x%=57.42.
5. Now we have two simple equations:
1) 100%=198
2) x%=57.42
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%=198/57.42
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 57.42 is what percent of 198

100%/x%=198/57.42
(100/x)*x=(198/57.42)*x       - we multiply both sides of the equation by x
100=3.448275862069*x       - we divide both sides of the equation by (3.448275862069) to get x
100/3.448275862069=x
29=x
x=29

now we have:
57.42 is 29% of 198
