What is 28.15 percent of 34.78 - 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 34.78 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 34.78 is 100%, so we can write it down as 34.78=100%.
4. We know, that x is 28.15% of the output value, so we can write it down as x=28.15%.
5. Now we have two simple equations:
1) 34.78=100%
2) x=28.15%
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:
34.78/x=100%/28.15%
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 28.15% of 34.78

34.78/x=100/28.15
(34.78/x)*x=(100/28.15)*x       - we multiply both sides of the equation by x
34.78=3.5523978685613*x       - we divide both sides of the equation by (3.5523978685613) to get x
34.78/3.5523978685613=x
9.79057=x
x=9.79057

now we have:
28.15% of 34.78=9.79057
