1247.4 is what percent of 8910 - 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 8910 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 8910, so we can write it down as 100%=8910.
4. We know, that x% equals 1247.4 of the output value, so we can write it down as x%=1247.4.
5. Now we have two simple equations:
1) 100%=8910
2) x%=1247.4
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%=8910/1247.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1247.4 is what percent of 8910

100%/x%=8910/1247.4
(100/x)*x=(8910/1247.4)*x       - we multiply both sides of the equation by x
100=7.1428571428571*x       - we divide both sides of the equation by (7.1428571428571) to get x
100/7.1428571428571=x
14=x
x=14

now we have:
1247.4 is 14% of 8910
