What is 0.0072 percent of 0.72 - 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 0.72 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 0.72 is 100%, so we can write it down as 0.72=100%.
4. We know, that x is 0.0072% of the output value, so we can write it down as x=0.0072%.
5. Now we have two simple equations:
1) 0.72=100%
2) x=0.0072%
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:
0.72/x=100%/0.0072%
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 0.0072% of 0.72

0.72/x=100/0.0072
(0.72/x)*x=(100/0.0072)*x       - we multiply both sides of the equation by x
0.72=13888.888888889*x       - we divide both sides of the equation by (13888.888888889) to get x
0.72/13888.888888889=x
5.184E-5=x
x=5.184E-5

now we have:
0.0072% of 0.72=5.184E-5
