What is 3.368 percent of 20.81 - 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 20.81 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 20.81 is 100%, so we can write it down as 20.81=100%.
4. We know, that x is 3.368% of the output value, so we can write it down as x=3.368%.
5. Now we have two simple equations:
1) 20.81=100%
2) x=3.368%
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:
20.81/x=100%/3.368%
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 3.368% of 20.81

20.81/x=100/3.368
(20.81/x)*x=(100/3.368)*x       - we multiply both sides of the equation by x
20.81=29.691211401425*x       - we divide both sides of the equation by (29.691211401425) to get x
20.81/29.691211401425=x
0.7008808=x
x=0.7008808

now we have:
3.368% of 20.81=0.7008808
