What is 6.8 percent of 515 - 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 515 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 515 is 100%, so we can write it down as 515=100%.
4. We know, that x is 6.8% of the output value, so we can write it down as x=6.8%.
5. Now we have two simple equations:
1) 515=100%
2) x=6.8%
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:
515/x=100%/6.8%
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 6.8% of 515

515/x=100/6.8
(515/x)*x=(100/6.8)*x       - we multiply both sides of the equation by x
515=14.705882352941*x       - we divide both sides of the equation by (14.705882352941) to get x
515/14.705882352941=x
35.02=x
x=35.02

now we have:
6.8% of 515=35.02
