What is 20 percent of 6831 - 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 6831 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 6831 is 100%, so we can write it down as 6831=100%.
4. We know, that x is 20% of the output value, so we can write it down as x=20%.
5. Now we have two simple equations:
1) 6831=100%
2) x=20%
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:
6831/x=100%/20%
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 20% of 6831

6831/x=100/20
(6831/x)*x=(100/20)*x       - we multiply both sides of the equation by x
6831=5*x       - we divide both sides of the equation by (5) to get x
6831/5=x
1366.2=x
x=1366.2

now we have:
20% of 6831=1366.2
