15.9 is what percent of 3.6 - 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 3.6 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 3.6, so we can write it down as 100%=3.6.
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%=3.6
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%=3.6/15.9
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 3.6

100%/x%=3.6/15.9
(100/x)*x=(3.6/15.9)*x       - we multiply both sides of the equation by x
100=0.22641509433962*x       - we divide both sides of the equation by (0.22641509433962) to get x
100/0.22641509433962=x
441.66666666667=x
x=441.66666666667

now we have:
15.9 is 441.66666666667% of 3.6
