31.29 is what percent of 31 - 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 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, so we can write it down as 100%=31.
4. We know, that x% equals 31.29 of the output value, so we can write it down as x%=31.29.
5. Now we have two simple equations:
1) 100%=31
2) x%=31.29
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%=31/31.29
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31.29 is what percent of 31

100%/x%=31/31.29
(100/x)*x=(31/31.29)*x       - we multiply both sides of the equation by x
100=0.99073186321508*x       - we divide both sides of the equation by (0.99073186321508) to get x
100/0.99073186321508=x
100.93548387097=x
x=100.93548387097

now we have:
31.29 is 100.93548387097% of 31
