What is 199900 percent of 20 - 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 20 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 20 is 100%, so we can write it down as 20=100%.
4. We know, that x is 199900% of the output value, so we can write it down as x=199900%.
5. Now we have two simple equations:
1) 20=100%
2) x=199900%
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:
20/x=100%/199900%
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 199900% of 20

20/x=100/199900
(20/x)*x=(100/199900)*x       - we multiply both sides of the equation by x
20=0.00050025012506253*x       - we divide both sides of the equation by (0.00050025012506253) to get x
20/0.00050025012506253=x
39980=x
x=39980

now we have:
199900% of 20=39980
