537.55 is what percent of 1540 - 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 1540 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 1540, so we can write it down as 100%=1540.
4. We know, that x% equals 537.55 of the output value, so we can write it down as x%=537.55.
5. Now we have two simple equations:
1) 100%=1540
2) x%=537.55
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%=1540/537.55
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 537.55 is what percent of 1540

100%/x%=1540/537.55
(100/x)*x=(1540/537.55)*x       - we multiply both sides of the equation by x
100=2.8648497814157*x       - we divide both sides of the equation by (2.8648497814157) to get x
100/2.8648497814157=x
34.905844155844=x
x=34.905844155844

now we have:
537.55 is 34.905844155844% of 1540
