31.88 is what percent of 2160 - 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 2160 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 2160, so we can write it down as 100%=2160.
4. We know, that x% equals 31.88 of the output value, so we can write it down as x%=31.88.
5. Now we have two simple equations:
1) 100%=2160
2) x%=31.88
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%=2160/31.88
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31.88 is what percent of 2160

100%/x%=2160/31.88
(100/x)*x=(2160/31.88)*x       - we multiply both sides of the equation by x
100=67.754077791719*x       - we divide both sides of the equation by (67.754077791719) to get x
100/67.754077791719=x
1.4759259259259=x
x=1.4759259259259

now we have:
31.88 is 1.4759259259259% of 2160
