What is 12.2 percent of 311000000 - 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 311000000 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 311000000 is 100%, so we can write it down as 311000000=100%.
4. We know, that x is 12.2% of the output value, so we can write it down as x=12.2%.
5. Now we have two simple equations:
1) 311000000=100%
2) x=12.2%
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:
311000000/x=100%/12.2%
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 12.2% of 311000000

311000000/x=100/12.2
(311000000/x)*x=(100/12.2)*x       - we multiply both sides of the equation by x
311000000=8.1967213114754*x       - we divide both sides of the equation by (8.1967213114754) to get x
311000000/8.1967213114754=x
37942000=x
x=37942000

now we have:
12.2% of 311000000=37942000
