What is 2 percent of 8639 - 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 8639 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 8639 is 100%, so we can write it down as 8639=100%.
4. We know, that x is 2% of the output value, so we can write it down as x=2%.
5. Now we have two simple equations:
1) 8639=100%
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:
8639/x=100%/2%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 2% of 8639

8639/x=100/2
(8639/x)*x=(100/2)*x       - we multiply both sides of the equation by x
8639=50*x       - we divide both sides of the equation by (50) to get x
8639/50=x
172.78=x
x=172.78

now we have:
2% of 8639=172.78
