16.15 is what percent of 78.85 - 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 78.85 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 100% equals 78.85, so we can write it down as 100%=78.85.
4. We know, that x% equals 16.15 of the output value, so we can write it down as x%=16.15.
5. Now we have two simple equations:
1) 100%=78.85
2) x%=16.15
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:
100%/x%=78.85/16.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 16.15 is what percent of 78.85

100%/x%=78.85/16.15
(100/x)*x=(78.85/16.15)*x       - we multiply both sides of the equation by x
100=4.8823529411765*x       - we divide both sides of the equation by (4.8823529411765) to get x
100/4.8823529411765=x
20.481927710843=x
x=20.481927710843

now we have:
16.15 is 20.481927710843% of 78.85
