610.5 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 610.5 of the output value, so we can write it down as x%=610.5.
5. Now we have two simple equations:
1) 100%=720
2) x%=610.5
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%=720/610.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 610.5 is what percent of 720

100%/x%=720/610.5
(100/x)*x=(720/610.5)*x       - we multiply both sides of the equation by x
100=1.1793611793612*x       - we divide both sides of the equation by (1.1793611793612) to get x
100/1.1793611793612=x
84.791666666667=x
x=84.791666666667

now we have:
610.5 is 84.791666666667% of 720
