915.82 is what percent of 990 - 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 990 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 990, so we can write it down as 100%=990.
4. We know, that x% equals 915.82 of the output value, so we can write it down as x%=915.82.
5. Now we have two simple equations:
1) 100%=990
2) x%=915.82
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%=990/915.82
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 915.82 is what percent of 990

100%/x%=990/915.82
(100/x)*x=(990/915.82)*x       - we multiply both sides of the equation by x
100=1.080998449477*x       - we divide both sides of the equation by (1.080998449477) to get x
100/1.080998449477=x
92.507070707071=x
x=92.507070707071

now we have:
915.82 is 92.507070707071% of 990
