314.5 is what percent of 431 - 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 431 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 431, so we can write it down as 100%=431.
4. We know, that x% equals 314.5 of the output value, so we can write it down as x%=314.5.
5. Now we have two simple equations:
1) 100%=431
2) x%=314.5
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%=431/314.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 314.5 is what percent of 431

100%/x%=431/314.5
(100/x)*x=(431/314.5)*x       - we multiply both sides of the equation by x
100=1.3704292527822*x       - we divide both sides of the equation by (1.3704292527822) to get x
100/1.3704292527822=x
72.969837587007=x
x=72.969837587007

now we have:
314.5 is 72.969837587007% of 431
