98.7 is what percent of 816 - 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 816 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 816, so we can write it down as 100%=816.
4. We know, that x% equals 98.7 of the output value, so we can write it down as x%=98.7.
5. Now we have two simple equations:
1) 100%=816
2) x%=98.7
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%=816/98.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 98.7 is what percent of 816

100%/x%=816/98.7
(100/x)*x=(816/98.7)*x       - we multiply both sides of the equation by x
100=8.2674772036474*x       - we divide both sides of the equation by (8.2674772036474) to get x
100/8.2674772036474=x
12.095588235294=x
x=12.095588235294

now we have:
98.7 is 12.095588235294% of 816
