13.17 is what percent of 169.99 - 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 169.99 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 169.99, so we can write it down as 100%=169.99.
4. We know, that x% equals 13.17 of the output value, so we can write it down as x%=13.17.
5. Now we have two simple equations:
1) 100%=169.99
2) x%=13.17
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%=169.99/13.17
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.17 is what percent of 169.99

100%/x%=169.99/13.17
(100/x)*x=(169.99/13.17)*x       - we multiply both sides of the equation by x
100=12.907365223994*x       - we divide both sides of the equation by (12.907365223994) to get x
100/12.907365223994=x
7.74751455968=x
x=7.74751455968

now we have:
13.17 is 7.74751455968% of 169.99
