What is 31.94 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 31.94% of the output value, so we can write it down as x=31.94%.
5. Now we have two simple equations:
1) 20=100%
2) x=31.94%
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%/31.94%
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 31.94% of 20

20/x=100/31.94
(20/x)*x=(100/31.94)*x       - we multiply both sides of the equation by x
20=3.1308703819662*x       - we divide both sides of the equation by (3.1308703819662) to get x
20/3.1308703819662=x
6.388=x
x=6.388

now we have:
31.94% of 20=6.388
