57.8 is what percent of 200.8 - 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 200.8 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 200.8, so we can write it down as 100%=200.8.
4. We know, that x% equals 57.8 of the output value, so we can write it down as x%=57.8.
5. Now we have two simple equations:
1) 100%=200.8
2) x%=57.8
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%=200.8/57.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 57.8 is what percent of 200.8

100%/x%=200.8/57.8
(100/x)*x=(200.8/57.8)*x       - we multiply both sides of the equation by x
100=3.4740484429066*x       - we divide both sides of the equation by (3.4740484429066) to get x
100/3.4740484429066=x
28.784860557769=x
x=28.784860557769

now we have:
57.8 is 28.784860557769% of 200.8
