12.5 is what percent of 203 - 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 203 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 203, so we can write it down as 100%=203.
4. We know, that x% equals 12.5 of the output value, so we can write it down as x%=12.5.
5. Now we have two simple equations:
1) 100%=203
2) x%=12.5
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%=203/12.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.5 is what percent of 203

100%/x%=203/12.5
(100/x)*x=(203/12.5)*x       - we multiply both sides of the equation by x
100=16.24*x       - we divide both sides of the equation by (16.24) to get x
100/16.24=x
6.1576354679803=x
x=6.1576354679803

now we have:
12.5 is 6.1576354679803% of 203
