What is 1.8 percent of 21851 - 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 21851 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 21851 is 100%, so we can write it down as 21851=100%.
4. We know, that x is 1.8% of the output value, so we can write it down as x=1.8%.
5. Now we have two simple equations:
1) 21851=100%
2) x=1.8%
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:
21851/x=100%/1.8%
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 1.8% of 21851

21851/x=100/1.8
(21851/x)*x=(100/1.8)*x       - we multiply both sides of the equation by x
21851=55.555555555556*x       - we divide both sides of the equation by (55.555555555556) to get x
21851/55.555555555556=x
393.318=x
x=393.318

now we have:
1.8% of 21851=393.318
