90.4 is what percent of 1317 - 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 1317 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 1317, so we can write it down as 100%=1317.
4. We know, that x% equals 90.4 of the output value, so we can write it down as x%=90.4.
5. Now we have two simple equations:
1) 100%=1317
2) x%=90.4
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%=1317/90.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 90.4 is what percent of 1317

100%/x%=1317/90.4
(100/x)*x=(1317/90.4)*x       - we multiply both sides of the equation by x
100=14.568584070796*x       - we divide both sides of the equation by (14.568584070796) to get x
100/14.568584070796=x
6.8640850417616=x
x=6.8640850417616

now we have:
90.4 is 6.8640850417616% of 1317
