15.9 is what percent of 111.7 - 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 111.7 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 111.7, so we can write it down as 100%=111.7.
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%=111.7
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%=111.7/15.9
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 111.7

100%/x%=111.7/15.9
(100/x)*x=(111.7/15.9)*x       - we multiply both sides of the equation by x
100=7.0251572327044*x       - we divide both sides of the equation by (7.0251572327044) to get x
100/7.0251572327044=x
14.234556848702=x
x=14.234556848702

now we have:
15.9 is 14.234556848702% of 111.7
