20 is what percent of 82.48 - 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 82.48 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 82.48, so we can write it down as 100%=82.48.
4. We know, that x% equals 20 of the output value, so we can write it down as x%=20.
5. Now we have two simple equations:
1) 100%=82.48
2) x%=20
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%=82.48/20
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20 is what percent of 82.48

100%/x%=82.48/20
(100/x)*x=(82.48/20)*x       - we multiply both sides of the equation by x
100=4.124*x       - we divide both sides of the equation by (4.124) to get x
100/4.124=x
24.248302618817=x
x=24.248302618817

now we have:
20 is 24.248302618817% of 82.48
