908.3 is what percent of 1045 - 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 1045 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 1045, so we can write it down as 100%=1045.
4. We know, that x% equals 908.3 of the output value, so we can write it down as x%=908.3.
5. Now we have two simple equations:
1) 100%=1045
2) x%=908.3
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%=1045/908.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 908.3 is what percent of 1045

100%/x%=1045/908.3
(100/x)*x=(1045/908.3)*x       - we multiply both sides of the equation by x
100=1.1505009358142*x       - we divide both sides of the equation by (1.1505009358142) to get x
100/1.1505009358142=x
86.918660287081=x
x=86.918660287081

now we have:
908.3 is 86.918660287081% of 1045
