12.5 is what percent of 177.8 - 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 177.8 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 177.8, so we can write it down as 100%=177.8.
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%=177.8
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%=177.8/12.5
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 177.8

100%/x%=177.8/12.5
(100/x)*x=(177.8/12.5)*x       - we multiply both sides of the equation by x
100=14.224*x       - we divide both sides of the equation by (14.224) to get x
100/14.224=x
7.0303712035996=x
x=7.0303712035996

now we have:
12.5 is 7.0303712035996% of 177.8
