20.2 is what percent of 235.7 - 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 235.7 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 235.7, so we can write it down as 100%=235.7.
4. We know, that x% equals 20.2 of the output value, so we can write it down as x%=20.2.
5. Now we have two simple equations:
1) 100%=235.7
2) x%=20.2
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%=235.7/20.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20.2 is what percent of 235.7

100%/x%=235.7/20.2
(100/x)*x=(235.7/20.2)*x       - we multiply both sides of the equation by x
100=11.668316831683*x       - we divide both sides of the equation by (11.668316831683) to get x
100/11.668316831683=x
8.5702163767501=x
x=8.5702163767501

now we have:
20.2 is 8.5702163767501% of 235.7
