2 is what percent of 20878 - 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 20878 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 20878, so we can write it down as 100%=20878.
4. We know, that x% equals 2 of the output value, so we can write it down as x%=2.
5. Now we have two simple equations:
1) 100%=20878
2) x%=2
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%=20878/2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2 is what percent of 20878

100%/x%=20878/2
(100/x)*x=(20878/2)*x       - we multiply both sides of the equation by x
100=10439*x       - we divide both sides of the equation by (10439) to get x
100/10439=x
0.0095794616342562=x
x=0.0095794616342562

now we have:
2 is 0.0095794616342562% of 20878
