216.58 is what percent of 720 - 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 720 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 720, so we can write it down as 100%=720.
4. We know, that x% equals 216.58 of the output value, so we can write it down as x%=216.58.
5. Now we have two simple equations:
1) 100%=720
2) x%=216.58
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%=720/216.58
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 216.58 is what percent of 720

100%/x%=720/216.58
(100/x)*x=(720/216.58)*x       - we multiply both sides of the equation by x
100=3.3244066857512*x       - we divide both sides of the equation by (3.3244066857512) to get x
100/3.3244066857512=x
30.080555555556=x
x=30.080555555556

now we have:
216.58 is 30.080555555556% of 720
