15 is what percent of 36.99 - 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 36.99 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 36.99, so we can write it down as 100%=36.99.
4. We know, that x% equals 15 of the output value, so we can write it down as x%=15.
5. Now we have two simple equations:
1) 100%=36.99
2) x%=15
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%=36.99/15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15 is what percent of 36.99

100%/x%=36.99/15
(100/x)*x=(36.99/15)*x       - we multiply both sides of the equation by x
100=2.466*x       - we divide both sides of the equation by (2.466) to get x
100/2.466=x
40.551500405515=x
x=40.551500405515

now we have:
15 is 40.551500405515% of 36.99
