40.25 is what percent of 2100 - 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 2100 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 2100, so we can write it down as 100%=2100.
4. We know, that x% equals 40.25 of the output value, so we can write it down as x%=40.25.
5. Now we have two simple equations:
1) 100%=2100
2) x%=40.25
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%=2100/40.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 40.25 is what percent of 2100

100%/x%=2100/40.25
(100/x)*x=(2100/40.25)*x       - we multiply both sides of the equation by x
100=52.173913043478*x       - we divide both sides of the equation by (52.173913043478) to get x
100/52.173913043478=x
1.9166666666667=x
x=1.9166666666667

now we have:
40.25 is 1.9166666666667% of 2100
