9.39 is what percent of 89.99 - 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 89.99 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 89.99, so we can write it down as 100%=89.99.
4. We know, that x% equals 9.39 of the output value, so we can write it down as x%=9.39.
5. Now we have two simple equations:
1) 100%=89.99
2) x%=9.39
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%=89.99/9.39
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9.39 is what percent of 89.99

100%/x%=89.99/9.39
(100/x)*x=(89.99/9.39)*x       - we multiply both sides of the equation by x
100=9.5835995740149*x       - we divide both sides of the equation by (9.5835995740149) to get x
100/9.5835995740149=x
10.434492721413=x
x=10.434492721413

now we have:
9.39 is 10.434492721413% of 89.99
