318.3 is what percent of 345 - 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 345 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 345, so we can write it down as 100%=345.
4. We know, that x% equals 318.3 of the output value, so we can write it down as x%=318.3.
5. Now we have two simple equations:
1) 100%=345
2) x%=318.3
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%=345/318.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 318.3 is what percent of 345

100%/x%=345/318.3
(100/x)*x=(345/318.3)*x       - we multiply both sides of the equation by x
100=1.0838831291235*x       - we divide both sides of the equation by (1.0838831291235) to get x
100/1.0838831291235=x
92.260869565217=x
x=92.260869565217

now we have:
318.3 is 92.260869565217% of 345
