13.65 is what percent of 34.45 - 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 34.45 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 34.45, so we can write it down as 100%=34.45.
4. We know, that x% equals 13.65 of the output value, so we can write it down as x%=13.65.
5. Now we have two simple equations:
1) 100%=34.45
2) x%=13.65
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%=34.45/13.65
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.65 is what percent of 34.45

100%/x%=34.45/13.65
(100/x)*x=(34.45/13.65)*x       - we multiply both sides of the equation by x
100=2.5238095238095*x       - we divide both sides of the equation by (2.5238095238095) to get x
100/2.5238095238095=x
39.622641509434=x
x=39.622641509434

now we have:
13.65 is 39.622641509434% of 34.45
