16.15 is what percent of 21.5 - 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 21.5 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 21.5, so we can write it down as 100%=21.5.
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%=21.5
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%=21.5/16.15
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 21.5

100%/x%=21.5/16.15
(100/x)*x=(21.5/16.15)*x       - we multiply both sides of the equation by x
100=1.3312693498452*x       - we divide both sides of the equation by (1.3312693498452) to get x
100/1.3312693498452=x
75.116279069767=x
x=75.116279069767

now we have:
16.15 is 75.116279069767% of 21.5
