What is 8.88 percent of 81 - 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 81 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 81 is 100%, so we can write it down as 81=100%.
4. We know, that x is 8.88% of the output value, so we can write it down as x=8.88%.
5. Now we have two simple equations:
1) 81=100%
2) x=8.88%
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:
81/x=100%/8.88%
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 8.88% of 81

81/x=100/8.88
(81/x)*x=(100/8.88)*x       - we multiply both sides of the equation by x
81=11.261261261261*x       - we divide both sides of the equation by (11.261261261261) to get x
81/11.261261261261=x
7.1928=x
x=7.1928

now we have:
8.88% of 81=7.1928
