819 is what percent of 2 - 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 2 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 2, so we can write it down as 100%=2.
4. We know, that x% equals 819 of the output value, so we can write it down as x%=819.
5. Now we have two simple equations:
1) 100%=2
2) x%=819
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%=2/819
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 819 is what percent of 2

100%/x%=2/819
(100/x)*x=(2/819)*x       - we multiply both sides of the equation by x
100=0.0024420024420024*x       - we divide both sides of the equation by (0.0024420024420024) to get x
100/0.0024420024420024=x
40950=x
x=40950

now we have:
819 is 40950% of 2
