221.73 is what percent of 31220 - 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 31220 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 31220, so we can write it down as 100%=31220.
4. We know, that x% equals 221.73 of the output value, so we can write it down as x%=221.73.
5. Now we have two simple equations:
1) 100%=31220
2) x%=221.73
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%=31220/221.73
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 221.73 is what percent of 31220

100%/x%=31220/221.73
(100/x)*x=(31220/221.73)*x       - we multiply both sides of the equation by x
100=140.80187615568*x       - we divide both sides of the equation by (140.80187615568) to get x
100/140.80187615568=x
0.71021780909673=x
x=0.71021780909673

now we have:
