172.8 is what percent of 236.7 - 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 236.7 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 236.7, so we can write it down as 100%=236.7.
4. We know, that x% equals 172.8 of the output value, so we can write it down as x%=172.8.
5. Now we have two simple equations:
1) 100%=236.7
2) x%=172.8
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%=236.7/172.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 172.8 is what percent of 236.7

100%/x%=236.7/172.8
(100/x)*x=(236.7/172.8)*x       - we multiply both sides of the equation by x
100=1.3697916666667*x       - we divide both sides of the equation by (1.3697916666667) to get x
100/1.3697916666667=x
73.003802281369=x
x=73.003802281369

now we have:
172.8 is 73.003802281369% of 236.7
