What is 0.04 percent of 51 - 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 51 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 51 is 100%, so we can write it down as 51=100%.
4. We know, that x is 0.04% of the output value, so we can write it down as x=0.04%.
5. Now we have two simple equations:
1) 51=100%
2) x=0.04%
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:
51/x=100%/0.04%
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 0.04% of 51

51/x=100/0.04
(51/x)*x=(100/0.04)*x       - we multiply both sides of the equation by x
51=2500*x       - we divide both sides of the equation by (2500) to get x
51/2500=x
0.0204=x
x=0.0204

now we have:
0.04% of 51=0.0204
