83.1 is what percent of 98.6 - 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 98.6 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 98.6, so we can write it down as 100%=98.6.
4. We know, that x% equals 83.1 of the output value, so we can write it down as x%=83.1.
5. Now we have two simple equations:
1) 100%=98.6
2) x%=83.1
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%=98.6/83.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 83.1 is what percent of 98.6

100%/x%=98.6/83.1
(100/x)*x=(98.6/83.1)*x       - we multiply both sides of the equation by x
100=1.1865222623345*x       - we divide both sides of the equation by (1.1865222623345) to get x
100/1.1865222623345=x
84.279918864097=x
x=84.279918864097

now we have:
83.1 is 84.279918864097% of 98.6
