0.08 is what percent of 0.004 - 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 0.004 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 100% equals 0.004, so we can write it down as 100%=0.004.
4. We know, that x% equals 0.08 of the output value, so we can write it down as x%=0.08.
5. Now we have two simple equations:
1) 100%=0.004
2) x%=0.08
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:
100%/x%=0.004/0.08
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.08 is what percent of 0.004

100%/x%=0.004/0.08
(100/x)*x=(0.004/0.08)*x       - we multiply both sides of the equation by x
100=0.05*x       - we divide both sides of the equation by (0.05) to get x
100/0.05=x
2000=x
x=2000

now we have:
0.08 is 2000% of 0.004
