18.75 is what percent of 172 - 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 172 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 172, so we can write it down as 100%=172.
4. We know, that x% equals 18.75 of the output value, so we can write it down as x%=18.75.
5. Now we have two simple equations:
1) 100%=172
2) x%=18.75
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%=172/18.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.75 is what percent of 172

100%/x%=172/18.75
(100/x)*x=(172/18.75)*x       - we multiply both sides of the equation by x
100=9.1733333333333*x       - we divide both sides of the equation by (9.1733333333333) to get x
100/9.1733333333333=x
10.901162790698=x
x=10.901162790698

now we have:
18.75 is 10.901162790698% of 172
