29.2 is what percent of 31.5 - 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 31.5 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 31.5, so we can write it down as 100%=31.5.
4. We know, that x% equals 29.2 of the output value, so we can write it down as x%=29.2.
5. Now we have two simple equations:
1) 100%=31.5
2) x%=29.2
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%=31.5/29.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 29.2 is what percent of 31.5

100%/x%=31.5/29.2
(100/x)*x=(31.5/29.2)*x       - we multiply both sides of the equation by x
100=1.0787671232877*x       - we divide both sides of the equation by (1.0787671232877) to get x
100/1.0787671232877=x
92.698412698413=x
x=92.698412698413

now we have:
29.2 is 92.698412698413% of 31.5
