90 is what percent of 8299 - 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 8299 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 8299, so we can write it down as 100%=8299.
4. We know, that x% equals 90 of the output value, so we can write it down as x%=90.
5. Now we have two simple equations:
1) 100%=8299
2) x%=90
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%=8299/90
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 90 is what percent of 8299

100%/x%=8299/90
(100/x)*x=(8299/90)*x       - we multiply both sides of the equation by x
100=92.211111111111*x       - we divide both sides of the equation by (92.211111111111) to get x
100/92.211111111111=x
1.0844680081938=x
x=1.0844680081938

now we have:
90 is 1.0844680081938% of 8299
