What is 3 percent of 19980 - 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 19980 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 19980 is 100%, so we can write it down as 19980=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) 19980=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:
19980/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 19980

19980/x=100/3
(19980/x)*x=(100/3)*x       - we multiply both sides of the equation by x
19980=33.333333333333*x       - we divide both sides of the equation by (33.333333333333) to get x
19980/33.333333333333=x
599.4=x
x=599.4

now we have:
3% of 19980=599.4
