321.1 is what percent of 918 - 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 918 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 918, so we can write it down as 100%=918.
4. We know, that x% equals 321.1 of the output value, so we can write it down as x%=321.1.
5. Now we have two simple equations:
1) 100%=918
2) x%=321.1
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%=918/321.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 321.1 is what percent of 918

100%/x%=918/321.1
(100/x)*x=(918/321.1)*x       - we multiply both sides of the equation by x
100=2.8589224540642*x       - we divide both sides of the equation by (2.8589224540642) to get x
100/2.8589224540642=x
34.978213507625=x
x=34.978213507625

now we have:
321.1 is 34.978213507625% of 918
