What is 7.65 percent of 27.86 - 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 27.86 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 27.86 is 100%, so we can write it down as 27.86=100%.
4. We know, that x is 7.65% of the output value, so we can write it down as x=7.65%.
5. Now we have two simple equations:
1) 27.86=100%
2) x=7.65%
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:
27.86/x=100%/7.65%
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 7.65% of 27.86

27.86/x=100/7.65
(27.86/x)*x=(100/7.65)*x       - we multiply both sides of the equation by x
27.86=13.071895424837*x       - we divide both sides of the equation by (13.071895424837) to get x
27.86/13.071895424837=x
2.13129=x
x=2.13129

now we have:
7.65% of 27.86=2.13129
