31.5 is what percent of 16 - 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 16 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 16, so we can write it down as 100%=16.
4. We know, that x% equals 31.5 of the output value, so we can write it down as x%=31.5.
5. Now we have two simple equations:
1) 100%=16
2) x%=31.5
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%=16/31.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31.5 is what percent of 16

100%/x%=16/31.5
(100/x)*x=(16/31.5)*x       - we multiply both sides of the equation by x
100=0.50793650793651*x       - we divide both sides of the equation by (0.50793650793651) to get x
100/0.50793650793651=x
196.875=x
x=196.875

now we have:
31.5 is 196.875% of 16
