321.4 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 321.4 of the output value, so we can write it down as x%=321.4.
5. Now we have two simple equations:
1) 100%=918
2) x%=321.4
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%=918/321.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 321.4 is what percent of 918

100%/x%=918/321.4
(100/x)*x=(918/321.4)*x       - we multiply both sides of the equation by x
100=2.8562538892346*x       - we divide both sides of the equation by (2.8562538892346) to get x
100/2.8562538892346=x
35.010893246187=x
x=35.010893246187

now we have:
321.4 is 35.010893246187% of 918
