What is 2.1 percent of 1803 - 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 1803 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 1803 is 100%, so we can write it down as 1803=100%.
4. We know, that x is 2.1% of the output value, so we can write it down as x=2.1%.
5. Now we have two simple equations:
1) 1803=100%
2) x=2.1%
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:
1803/x=100%/2.1%
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 2.1% of 1803

1803/x=100/2.1
(1803/x)*x=(100/2.1)*x       - we multiply both sides of the equation by x
1803=47.619047619048*x       - we divide both sides of the equation by (47.619047619048) to get x
1803/47.619047619048=x
37.863=x
x=37.863

now we have:
2.1% of 1803=37.863
