What is 0.15 percent of 128.44 - 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 128.44 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 128.44 is 100%, so we can write it down as 128.44=100%.
4. We know, that x is 0.15% of the output value, so we can write it down as x=0.15%.
5. Now we have two simple equations:
1) 128.44=100%
2) x=0.15%
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:
128.44/x=100%/0.15%
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 0.15% of 128.44

128.44/x=100/0.15
(128.44/x)*x=(100/0.15)*x       - we multiply both sides of the equation by x
128.44=666.66666666667*x       - we divide both sides of the equation by (666.66666666667) to get x
128.44/666.66666666667=x
0.19266=x
x=0.19266

now we have:
0.15% of 128.44=0.19266
