What is 4.17 percent of 123 - 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 123 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 123 is 100%, so we can write it down as 123=100%.
4. We know, that x is 4.17% of the output value, so we can write it down as x=4.17%.
5. Now we have two simple equations:
1) 123=100%
2) x=4.17%
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:
123/x=100%/4.17%
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 4.17% of 123

123/x=100/4.17
(123/x)*x=(100/4.17)*x       - we multiply both sides of the equation by x
123=23.980815347722*x       - we divide both sides of the equation by (23.980815347722) to get x
123/23.980815347722=x
5.1291=x
x=5.1291

now we have:
4.17% of 123=5.1291
