What is 88.15 percent of 128.99 - 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 128.99 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 128.99 is 100%, so we can write it down as 128.99=100%.
4. We know, that x is 88.15% of the output value, so we can write it down as x=88.15%.
5. Now we have two simple equations:
1) 128.99=100%
2) x=88.15%
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:
128.99/x=100%/88.15%
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 88.15% of 128.99

128.99/x=100/88.15
(128.99/x)*x=(100/88.15)*x       - we multiply both sides of the equation by x
128.99=1.1344299489507*x       - we divide both sides of the equation by (1.1344299489507) to get x
128.99/1.1344299489507=x
113.704685=x
x=113.704685

now we have:
88.15% of 128.99=113.704685
