18.6 is what percent of 2.2 - 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 2.2 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 2.2, so we can write it down as 100%=2.2.
4. We know, that x% equals 18.6 of the output value, so we can write it down as x%=18.6.
5. Now we have two simple equations:
1) 100%=2.2
2) x%=18.6
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%=2.2/18.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.6 is what percent of 2.2

100%/x%=2.2/18.6
(100/x)*x=(2.2/18.6)*x       - we multiply both sides of the equation by x
100=0.11827956989247*x       - we divide both sides of the equation by (0.11827956989247) to get x
100/0.11827956989247=x
845.45454545455=x
x=845.45454545455

now we have:
18.6 is 845.45454545455% of 2.2
