What is 4.19 percent of 109 - 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 109 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 109 is 100%, so we can write it down as 109=100%.
4. We know, that x is 4.19% of the output value, so we can write it down as x=4.19%.
5. Now we have two simple equations:
1) 109=100%
2) x=4.19%
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:
109/x=100%/4.19%
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 4.19% of 109

109/x=100/4.19
(109/x)*x=(100/4.19)*x       - we multiply both sides of the equation by x
109=23.866348448687*x       - we divide both sides of the equation by (23.866348448687) to get x
109/23.866348448687=x
4.5671=x
x=4.5671

now we have:
4.19% of 109=4.5671
