15.2 is what percent of 1520.57 - 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 1520.57 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 1520.57, so we can write it down as 100%=1520.57.
4. We know, that x% equals 15.2 of the output value, so we can write it down as x%=15.2.
5. Now we have two simple equations:
1) 100%=1520.57
2) x%=15.2
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%=1520.57/15.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.2 is what percent of 1520.57

100%/x%=1520.57/15.2
(100/x)*x=(1520.57/15.2)*x       - we multiply both sides of the equation by x
100=100.0375*x       - we divide both sides of the equation by (100.0375) to get x
100/100.0375=x
0.99962514057229=x
x=0.99962514057229

now we have:
15.2 is 0.99962514057229% of 1520.57
