15.9 is what percent of 18000 - 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 18000 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 18000, so we can write it down as 100%=18000.
4. We know, that x% equals 15.9 of the output value, so we can write it down as x%=15.9.
5. Now we have two simple equations:
1) 100%=18000
2) x%=15.9
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%=18000/15.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.9 is what percent of 18000

100%/x%=18000/15.9
(100/x)*x=(18000/15.9)*x       - we multiply both sides of the equation by x
100=1132.0754716981*x       - we divide both sides of the equation by (1132.0754716981) to get x
100/1132.0754716981=x
0.088333333333333=x
x=0.088333333333333

now we have:
15.9 is 0.088333333333333% of 18000
