163.8 is what percent of 250 - 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 250 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 250, so we can write it down as 100%=250.
4. We know, that x% equals 163.8 of the output value, so we can write it down as x%=163.8.
5. Now we have two simple equations:
1) 100%=250
2) x%=163.8
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%=250/163.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 163.8 is what percent of 250

100%/x%=250/163.8
(100/x)*x=(250/163.8)*x       - we multiply both sides of the equation by x
100=1.5262515262515*x       - we divide both sides of the equation by (1.5262515262515) to get x
100/1.5262515262515=x
65.52=x
x=65.52

now we have:
163.8 is 65.52% of 250
