What is 3 percent of 20830 - 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 20830 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 20830 is 100%, so we can write it down as 20830=100%.
4. We know, that x is 3% of the output value, so we can write it down as x=3%.
5. Now we have two simple equations:
1) 20830=100%
2) x=3%
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:
20830/x=100%/3%
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 3% of 20830

20830/x=100/3
(20830/x)*x=(100/3)*x       - we multiply both sides of the equation by x
20830=33.333333333333*x       - we divide both sides of the equation by (33.333333333333) to get x
20830/33.333333333333=x
624.9=x
x=624.9

now we have:
3% of 20830=624.9
