What is 2.8 percent of 28.8 - 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 28.8 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 28.8 is 100%, so we can write it down as 28.8=100%.
4. We know, that x is 2.8% of the output value, so we can write it down as x=2.8%.
5. Now we have two simple equations:
1) 28.8=100%
2) x=2.8%
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:
28.8/x=100%/2.8%
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 2.8% of 28.8

28.8/x=100/2.8
(28.8/x)*x=(100/2.8)*x       - we multiply both sides of the equation by x
28.8=35.714285714286*x       - we divide both sides of the equation by (35.714285714286) to get x
28.8/35.714285714286=x
0.8064=x
x=0.8064

now we have:
2.8% of 28.8=0.8064
