What is 24 percent of 0.0004 - 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 0.0004 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 0.0004 is 100%, so we can write it down as 0.0004=100%.
4. We know, that x is 24% of the output value, so we can write it down as x=24%.
5. Now we have two simple equations:
1) 0.0004=100%
2) x=24%
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:
0.0004/x=100%/24%
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 24% of 0.0004

0.0004/x=100/24
(0.0004/x)*x=(100/24)*x       - we multiply both sides of the equation by x
0.0004=4.1666666666667*x       - we divide both sides of the equation by (4.1666666666667) to get x
0.0004/4.1666666666667=x
9.6E-5=x
x=9.6E-5

now we have:
24% of 0.0004=9.6E-5
