What is 3969 percent of 0.5 - 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 0.5 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 0.5 is 100%, so we can write it down as 0.5=100%.
4. We know, that x is 3969% of the output value, so we can write it down as x=3969%.
5. Now we have two simple equations:
1) 0.5=100%
2) x=3969%
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:
0.5/x=100%/3969%
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 3969% of 0.5

0.5/x=100/3969
(0.5/x)*x=(100/3969)*x       - we multiply both sides of the equation by x
0.5=0.025195263290501*x       - we divide both sides of the equation by (0.025195263290501) to get x
0.5/0.025195263290501=x
19.845=x
x=19.845

now we have:
3969% of 0.5=19.845
