What is 3.1 percent of 280000 - 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 280000 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 280000 is 100%, so we can write it down as 280000=100%.
4. We know, that x is 3.1% of the output value, so we can write it down as x=3.1%.
5. Now we have two simple equations:
1) 280000=100%
2) x=3.1%
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:
280000/x=100%/3.1%
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 3.1% of 280000

280000/x=100/3.1
(280000/x)*x=(100/3.1)*x       - we multiply both sides of the equation by x
280000=32.258064516129*x       - we divide both sides of the equation by (32.258064516129) to get x
280000/32.258064516129=x
8680=x
x=8680

now we have:
3.1% of 280000=8680
