48.5 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 48.5 of the output value, so we can write it down as x%=48.5.
5. Now we have two simple equations:
1) 100%=250
2) x%=48.5
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%=250/48.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 48.5 is what percent of 250

100%/x%=250/48.5
(100/x)*x=(250/48.5)*x       - we multiply both sides of the equation by x
100=5.1546391752577*x       - we divide both sides of the equation by (5.1546391752577) to get x
100/5.1546391752577=x
19.4=x
x=19.4

now we have:
48.5 is 19.4% of 250
