38.49 is what percent of 540 - 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 540 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 540, so we can write it down as 100%=540.
4. We know, that x% equals 38.49 of the output value, so we can write it down as x%=38.49.
5. Now we have two simple equations:
1) 100%=540
2) x%=38.49
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%=540/38.49
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 38.49 is what percent of 540

100%/x%=540/38.49
(100/x)*x=(540/38.49)*x       - we multiply both sides of the equation by x
100=14.029618082619*x       - we divide both sides of the equation by (14.029618082619) to get x
100/14.029618082619=x
7.1277777777778=x
x=7.1277777777778

now we have:
38.49 is 7.1277777777778% of 540
