17.8 is what percent of 125 - 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 125 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 125, so we can write it down as 100%=125.
4. We know, that x% equals 17.8 of the output value, so we can write it down as x%=17.8.
5. Now we have two simple equations:
1) 100%=125
2) x%=17.8
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%=125/17.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.8 is what percent of 125

100%/x%=125/17.8
(100/x)*x=(125/17.8)*x       - we multiply both sides of the equation by x
100=7.0224719101124*x       - we divide both sides of the equation by (7.0224719101124) to get x
100/7.0224719101124=x
14.24=x
x=14.24

now we have:
17.8 is 14.24% of 125
