23.7 is what percent of 320.9 - 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 320.9 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 320.9, so we can write it down as 100%=320.9.
4. We know, that x% equals 23.7 of the output value, so we can write it down as x%=23.7.
5. Now we have two simple equations:
1) 100%=320.9
2) x%=23.7
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%=320.9/23.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 23.7 is what percent of 320.9

100%/x%=320.9/23.7
(100/x)*x=(320.9/23.7)*x       - we multiply both sides of the equation by x
100=13.540084388186*x       - we divide both sides of the equation by (13.540084388186) to get x
100/13.540084388186=x
7.3854783421627=x
x=7.3854783421627

now we have:
23.7 is 7.3854783421627% of 320.9
