20.3 is what percent of 57.6 - 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 57.6 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 57.6, so we can write it down as 100%=57.6.
4. We know, that x% equals 20.3 of the output value, so we can write it down as x%=20.3.
5. Now we have two simple equations:
1) 100%=57.6
2) x%=20.3
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%=57.6/20.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20.3 is what percent of 57.6

100%/x%=57.6/20.3
(100/x)*x=(57.6/20.3)*x       - we multiply both sides of the equation by x
100=2.8374384236453*x       - we divide both sides of the equation by (2.8374384236453) to get x
100/2.8374384236453=x
35.243055555556=x
x=35.243055555556

now we have:
20.3 is 35.243055555556% of 57.6
