What is 3.5 percent of 18000 - 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 18000 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 18000 is 100%, so we can write it down as 18000=100%.
4. We know, that x is 3.5% of the output value, so we can write it down as x=3.5%.
5. Now we have two simple equations:
1) 18000=100%
2) x=3.5%
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:
18000/x=100%/3.5%
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 3.5% of 18000

18000/x=100/3.5
(18000/x)*x=(100/3.5)*x       - we multiply both sides of the equation by x
18000=28.5714285714*x       - we divide both sides of the equation by (28.5714285714) to get x
18000/28.5714285714=x
630=x
x=630

now we have:
3.5% of 18000=630
