20.86 is what percent of 57.96 - 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 57.96 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 57.96, so we can write it down as 100%=57.96.
4. We know, that x% equals 20.86 of the output value, so we can write it down as x%=20.86.
5. Now we have two simple equations:
1) 100%=57.96
2) x%=20.86
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%=57.96/20.86
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20.86 is what percent of 57.96

100%/x%=57.96/20.86
(100/x)*x=(57.96/20.86)*x       - we multiply both sides of the equation by x
100=2.7785234899329*x       - we divide both sides of the equation by (2.7785234899329) to get x
100/2.7785234899329=x
35.990338164251=x
x=35.990338164251

now we have:
20.86 is 35.990338164251% of 57.96
