20.88 is what percent of 166 - 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 166 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 166, so we can write it down as 100%=166.
4. We know, that x% equals 20.88 of the output value, so we can write it down as x%=20.88.
5. Now we have two simple equations:
1) 100%=166
2) x%=20.88
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%=166/20.88
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20.88 is what percent of 166

100%/x%=166/20.88
(100/x)*x=(166/20.88)*x       - we multiply both sides of the equation by x
100=7.9501915708812*x       - we divide both sides of the equation by (7.9501915708812) to get x
100/7.9501915708812=x
12.578313253012=x
x=12.578313253012

now we have:
20.88 is 12.578313253012% of 166
