What is 3995 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 3995% of the output value, so we can write it down as x=3995%.
5. Now we have two simple equations:
1) 20=100%
2) x=3995%
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%/3995%
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 3995% of 20

20/x=100/3995
(20/x)*x=(100/3995)*x       - we multiply both sides of the equation by x
20=0.025031289111389*x       - we divide both sides of the equation by (0.025031289111389) to get x
20/0.025031289111389=x
799=x
x=799

now we have:
3995% of 20=799
