122.57 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 122.57 of the output value, so we can write it down as x%=122.57.
5. Now we have two simple equations:
1) 100%=1540
2) x%=122.57
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%=1540/122.57
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 122.57 is what percent of 1540

100%/x%=1540/122.57
(100/x)*x=(1540/122.57)*x       - we multiply both sides of the equation by x
100=12.564249000571*x       - we divide both sides of the equation by (12.564249000571) to get x
100/12.564249000571=x
7.9590909090909=x
x=7.9590909090909

now we have:
122.57 is 7.9590909090909% of 1540
