15.9 is what percent of 30600 - 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 30600 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 30600, so we can write it down as 100%=30600.
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%=30600
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%=30600/15.9
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 30600

100%/x%=30600/15.9
(100/x)*x=(30600/15.9)*x       - we multiply both sides of the equation by x
100=1924.5283018868*x       - we divide both sides of the equation by (1924.5283018868) to get x
100/1924.5283018868=x
0.051960784313725=x
x=0.051960784313725

now we have:
15.9 is 0.051960784313725% of 30600
