What is 4.1 percent of 12.99 - 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 12.99 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 12.99 is 100%, so we can write it down as 12.99=100%.
4. We know, that x is 4.1% of the output value, so we can write it down as x=4.1%.
5. Now we have two simple equations:
1) 12.99=100%
2) x=4.1%
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:
12.99/x=100%/4.1%
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 4.1% of 12.99

12.99/x=100/4.1
(12.99/x)*x=(100/4.1)*x       - we multiply both sides of the equation by x
12.99=24.390243902439*x       - we divide both sides of the equation by (24.390243902439) to get x
12.99/24.390243902439=x
0.53259=x
x=0.53259

now we have:
4.1% of 12.99=0.53259
