902.4 is what percent of 1249 - 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 1249 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 1249, so we can write it down as 100%=1249.
4. We know, that x% equals 902.4 of the output value, so we can write it down as x%=902.4.
5. Now we have two simple equations:
1) 100%=1249
2) x%=902.4
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%=1249/902.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 902.4 is what percent of 1249

100%/x%=1249/902.4
(100/x)*x=(1249/902.4)*x       - we multiply both sides of the equation by x
100=1.3840868794326*x       - we divide both sides of the equation by (1.3840868794326) to get x
100/1.3840868794326=x
72.249799839872=x
x=72.249799839872

now we have:
902.4 is 72.249799839872% of 1249
