What is 82 percent of 128.5 - 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 128.5 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 128.5 is 100%, so we can write it down as 128.5=100%.
4. We know, that x is 82% of the output value, so we can write it down as x=82%.
5. Now we have two simple equations:
1) 128.5=100%
2) x=82%
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:
128.5/x=100%/82%
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 82% of 128.5

128.5/x=100/82
(128.5/x)*x=(100/82)*x       - we multiply both sides of the equation by x
128.5=1.219512195122*x       - we divide both sides of the equation by (1.219512195122) to get x
128.5/1.219512195122=x
105.37=x
x=105.37

now we have:
82% of 128.5=105.37
