20.9 is what percent of 16.6 - 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 16.6 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 16.6, so we can write it down as 100%=16.6.
4. We know, that x% equals 20.9 of the output value, so we can write it down as x%=20.9.
5. Now we have two simple equations:
1) 100%=16.6
2) x%=20.9
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%=16.6/20.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20.9 is what percent of 16.6

100%/x%=16.6/20.9
(100/x)*x=(16.6/20.9)*x       - we multiply both sides of the equation by x
100=0.79425837320574*x       - we divide both sides of the equation by (0.79425837320574) to get x
100/0.79425837320574=x
125.90361445783=x
x=125.90361445783

now we have:
20.9 is 125.90361445783% of 16.6
