What is 1.99 percent of 21.199 - 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 21.199 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 21.199 is 100%, so we can write it down as 21.199=100%.
4. We know, that x is 1.99% of the output value, so we can write it down as x=1.99%.
5. Now we have two simple equations:
1) 21.199=100%
2) x=1.99%
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:
21.199/x=100%/1.99%
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 1.99% of 21.199

21.199/x=100/1.99
(21.199/x)*x=(100/1.99)*x       - we multiply both sides of the equation by x
21.199=50.251256281407*x       - we divide both sides of the equation by (50.251256281407) to get x
21.199/50.251256281407=x
0.4218601=x
x=0.4218601

now we have:
1.99% of 21.199=0.4218601
