15.99 is what percent of 50 - 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 50 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 50, so we can write it down as 100%=50.
4. We know, that x% equals 15.99 of the output value, so we can write it down as x%=15.99.
5. Now we have two simple equations:
1) 100%=50
2) x%=15.99
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%=50/15.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.99 is what percent of 50

100%/x%=50/15.99
(100/x)*x=(50/15.99)*x       - we multiply both sides of the equation by x
100=3.1269543464665*x       - we divide both sides of the equation by (3.1269543464665) to get x
100/3.1269543464665=x
31.98=x
x=31.98

now we have:
15.99 is 31.98% of 50
