What is 2 percent of 128.04 - 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 128.04 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 128.04 is 100%, so we can write it down as 128.04=100%.
4. We know, that x is 2% of the output value, so we can write it down as x=2%.
5. Now we have two simple equations:
1) 128.04=100%
2) x=2%
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:
128.04/x=100%/2%
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 2% of 128.04

128.04/x=100/2
(128.04/x)*x=(100/2)*x       - we multiply both sides of the equation by x
128.04=50*x       - we divide both sides of the equation by (50) to get x
128.04/50=x
2.5608=x
x=2.5608

now we have:
2% of 128.04=2.5608
