What is 7.89 percent of 128000 - 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 128000 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 128000 is 100%, so we can write it down as 128000=100%.
4. We know, that x is 7.89% of the output value, so we can write it down as x=7.89%.
5. Now we have two simple equations:
1) 128000=100%
2) x=7.89%
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:
128000/x=100%/7.89%
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 7.89% of 128000

128000/x=100/7.89
(128000/x)*x=(100/7.89)*x       - we multiply both sides of the equation by x
128000=12.674271229404*x       - we divide both sides of the equation by (12.674271229404) to get x
128000/12.674271229404=x
10099.2=x
x=10099.2

now we have:
7.89% of 128000=10099.2
