13.29 is what percent of 38 - 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 38 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 38, so we can write it down as 100%=38.
4. We know, that x% equals 13.29 of the output value, so we can write it down as x%=13.29.
5. Now we have two simple equations:
1) 100%=38
2) x%=13.29
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%=38/13.29
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.29 is what percent of 38

100%/x%=38/13.29
(100/x)*x=(38/13.29)*x       - we multiply both sides of the equation by x
100=2.8592927012792*x       - we divide both sides of the equation by (2.8592927012792) to get x
100/2.8592927012792=x
34.973684210526=x
x=34.973684210526

now we have:
13.29 is 34.973684210526% of 38
