549.9 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 549.9 of the output value, so we can write it down as x%=549.9.
5. Now we have two simple equations:
1) 100%=720
2) x%=549.9
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%=720/549.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 549.9 is what percent of 720

100%/x%=720/549.9
(100/x)*x=(720/549.9)*x       - we multiply both sides of the equation by x
100=1.3093289689034*x       - we divide both sides of the equation by (1.3093289689034) to get x
100/1.3093289689034=x
76.375=x
x=76.375

now we have:
549.9 is 76.375% of 720
