What is 0.8889 percent of 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 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 72 is 100%, so we can write it down as 72=100%.
4. We know, that x is 0.8889% of the output value, so we can write it down as x=0.8889%.
5. Now we have two simple equations:
1) 72=100%
2) x=0.8889%
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:
72/x=100%/0.8889%
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 0.8889% of 72

72/x=100/0.8889
(72/x)*x=(100/0.8889)*x       - we multiply both sides of the equation by x
72=112.49859376758*x       - we divide both sides of the equation by (112.49859376758) to get x
72/112.49859376758=x
0.640008=x
x=0.640008

now we have:
0.8889% of 72=0.640008
