78.85 is what percent of 499 - 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 499 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 100% equals 499, so we can write it down as 100%=499.
4. We know, that x% equals 78.85 of the output value, so we can write it down as x%=78.85.
5. Now we have two simple equations:
1) 100%=499
2) x%=78.85
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:
100%/x%=499/78.85
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 78.85 is what percent of 499

100%/x%=499/78.85
(100/x)*x=(499/78.85)*x       - we multiply both sides of the equation by x
100=6.3284717818643*x       - we divide both sides of the equation by (6.3284717818643) to get x
100/6.3284717818643=x
15.801603206413=x
x=15.801603206413

now we have:
78.85 is 15.801603206413% of 499
