124.8 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 124.8 of the output value, so we can write it down as x%=124.8.
5. Now we have two simple equations:
1) 100%=172
2) x%=124.8
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%=172/124.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 124.8 is what percent of 172

100%/x%=172/124.8
(100/x)*x=(172/124.8)*x       - we multiply both sides of the equation by x
100=1.3782051282051*x       - we divide both sides of the equation by (1.3782051282051) to get x
100/1.3782051282051=x
72.558139534884=x
x=72.558139534884

now we have:
124.8 is 72.558139534884% of 172
