25 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 25 of the output value, so we can write it down as x%=25.
5. Now we have two simple equations:
1) 100%=177.8
2) x%=25
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%=177.8/25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 25 is what percent of 177.8

100%/x%=177.8/25
(100/x)*x=(177.8/25)*x       - we multiply both sides of the equation by x
100=7.112*x       - we divide both sides of the equation by (7.112) to get x
100/7.112=x
14.060742407199=x
x=14.060742407199

now we have:
25 is 14.060742407199% of 177.8
