8.99 is what percent of 10.39 - 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 10.39 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 10.39, so we can write it down as 100%=10.39.
4. We know, that x% equals 8.99 of the output value, so we can write it down as x%=8.99.
5. Now we have two simple equations:
1) 100%=10.39
2) x%=8.99
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%=10.39/8.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.99 is what percent of 10.39

100%/x%=10.39/8.99
(100/x)*x=(10.39/8.99)*x       - we multiply both sides of the equation by x
100=1.1557285873192*x       - we divide both sides of the equation by (1.1557285873192) to get x
100/1.1557285873192=x
86.525505293551=x
x=86.525505293551

now we have:
8.99 is 86.525505293551% of 10.39
