15 is what percent of 22000 - 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 22000 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 22000, so we can write it down as 100%=22000.
4. We know, that x% equals 15 of the output value, so we can write it down as x%=15.
5. Now we have two simple equations:
1) 100%=22000
2) x%=15
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%=22000/15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15 is what percent of 22000

100%/x%=22000/15
(100/x)*x=(22000/15)*x       - we multiply both sides of the equation by x
100=1466.6666666667*x       - we divide both sides of the equation by (1466.6666666667) to get x
100/1466.6666666667=x
0.068181818181818=x
x=0.068181818181818

now we have:
15 is 0.068181818181818% of 22000
