What is 12999 percent of 3 - 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 3 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 3 is 100%, so we can write it down as 3=100%.
4. We know, that x is 12999% of the output value, so we can write it down as x=12999%.
5. Now we have two simple equations:
1) 3=100%
2) x=12999%
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:
3/x=100%/12999%
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 12999% of 3

3/x=100/12999
(3/x)*x=(100/12999)*x       - we multiply both sides of the equation by x
3=0.0076928994538041*x       - we divide both sides of the equation by (0.0076928994538041) to get x
3/0.0076928994538041=x
389.97=x
x=389.97

now we have:
12999% of 3=389.97
