What is 5.05 percent of 18 - 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 18 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 18 is 100%, so we can write it down as 18=100%.
4. We know, that x is 5.05% of the output value, so we can write it down as x=5.05%.
5. Now we have two simple equations:
1) 18=100%
2) x=5.05%
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:
18/x=100%/5.05%
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 5.05% of 18

18/x=100/5.05
(18/x)*x=(100/5.05)*x       - we multiply both sides of the equation by x
18=19.80198019802*x       - we divide both sides of the equation by (19.80198019802) to get x
18/19.80198019802=x
0.909=x
x=0.909

now we have:
5.05% of 18=0.909
