What is 3.33 percent of 831 - 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 831 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 831 is 100%, so we can write it down as 831=100%.
4. We know, that x is 3.33% of the output value, so we can write it down as x=3.33%.
5. Now we have two simple equations:
1) 831=100%
2) x=3.33%
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:
831/x=100%/3.33%
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 3.33% of 831

831/x=100/3.33
(831/x)*x=(100/3.33)*x       - we multiply both sides of the equation by x
831=30.03003003003*x       - we divide both sides of the equation by (30.03003003003) to get x
831/30.03003003003=x
27.6723=x
x=27.6723

now we have:
3.33% of 831=27.6723
