What is 28.8 percent of 10.2 - 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 10.2 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 10.2 is 100%, so we can write it down as 10.2=100%.
4. We know, that x is 28.8% of the output value, so we can write it down as x=28.8%.
5. Now we have two simple equations:
1) 10.2=100%
2) x=28.8%
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:
10.2/x=100%/28.8%
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 28.8% of 10.2

10.2/x=100/28.8
(10.2/x)*x=(100/28.8)*x       - we multiply both sides of the equation by x
10.2=3.4722222222222*x       - we divide both sides of the equation by (3.4722222222222) to get x
10.2/3.4722222222222=x
2.9376=x
x=2.9376

now we have:
28.8% of 10.2=2.9376
