What is 0.72 percent of 139 - 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 139 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 139 is 100%, so we can write it down as 139=100%.
4. We know, that x is 0.72% of the output value, so we can write it down as x=0.72%.
5. Now we have two simple equations:
1) 139=100%
2) x=0.72%
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:
139/x=100%/0.72%
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 0.72% of 139

139/x=100/0.72
(139/x)*x=(100/0.72)*x       - we multiply both sides of the equation by x
139=138.88888888889*x       - we divide both sides of the equation by (138.88888888889) to get x
139/138.88888888889=x
1.0008=x
x=1.0008

now we have:
0.72% of 139=1.0008
