16.6 is what percent of 216.6 - 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 216.6 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 216.6, so we can write it down as 100%=216.6.
4. We know, that x% equals 16.6 of the output value, so we can write it down as x%=16.6.
5. Now we have two simple equations:
1) 100%=216.6
2) x%=16.6
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%=216.6/16.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 16.6 is what percent of 216.6

100%/x%=216.6/16.6
(100/x)*x=(216.6/16.6)*x       - we multiply both sides of the equation by x
100=13.048192771084*x       - we divide both sides of the equation by (13.048192771084) to get x
100/13.048192771084=x
7.6638965835642=x
x=7.6638965835642

now we have:
16.6 is 7.6638965835642% of 216.6
