137.73 is what percent of 1515 - 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 1515 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 1515, so we can write it down as 100%=1515.
4. We know, that x% equals 137.73 of the output value, so we can write it down as x%=137.73.
5. Now we have two simple equations:
1) 100%=1515
2) x%=137.73
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%=1515/137.73
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 137.73 is what percent of 1515

100%/x%=1515/137.73
(100/x)*x=(1515/137.73)*x       - we multiply both sides of the equation by x
100=10.999782182531*x       - we divide both sides of the equation by (10.999782182531) to get x
100/10.999782182531=x
9.0910891089109=x
x=9.0910891089109

now we have:
137.73 is 9.0910891089109% of 1515
