What is 0.004 percent of 86400 - 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 86400 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 86400 is 100%, so we can write it down as 86400=100%.
4. We know, that x is 0.004% of the output value, so we can write it down as x=0.004%.
5. Now we have two simple equations:
1) 86400=100%
2) x=0.004%
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:
86400/x=100%/0.004%
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 0.004% of 86400

86400/x=100/0.004
(86400/x)*x=(100/0.004)*x       - we multiply both sides of the equation by x
86400=25000*x       - we divide both sides of the equation by (25000) to get x
86400/25000=x
3.456=x
x=3.456

now we have:
0.004% of 86400=3.456
