What is 1.8 percent of 1125 - 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 1125 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 1125 is 100%, so we can write it down as 1125=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) 1125=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:
1125/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 1125

1125/x=100/1.8
(1125/x)*x=(100/1.8)*x       - we multiply both sides of the equation by x
1125=55.555555555556*x       - we divide both sides of the equation by (55.555555555556) to get x
1125/55.555555555556=x
20.25=x
x=20.25

now we have:
1.8% of 1125=20.25
