What is 15.15 percent of 66.85 - 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 66.85 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 66.85 is 100%, so we can write it down as 66.85=100%.
4. We know, that x is 15.15% of the output value, so we can write it down as x=15.15%.
5. Now we have two simple equations:
1) 66.85=100%
2) x=15.15%
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:
66.85/x=100%/15.15%
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 15.15% of 66.85

66.85/x=100/15.15
(66.85/x)*x=(100/15.15)*x       - we multiply both sides of the equation by x
66.85=6.6006600660066*x       - we divide both sides of the equation by (6.6006600660066) to get x
66.85/6.6006600660066=x
10.127775=x
x=10.127775

now we have:
15.15% of 66.85=10.127775
