655.29 is what percent of 728.1 - 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 728.1 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 728.1, so we can write it down as 100%=728.1.
4. We know, that x% equals 655.29 of the output value, so we can write it down as x%=655.29.
5. Now we have two simple equations:
1) 100%=728.1
2) x%=655.29
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%=728.1/655.29
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 655.29 is what percent of 728.1

100%/x%=728.1/655.29
(100/x)*x=(728.1/655.29)*x       - we multiply both sides of the equation by x
100=1.1111111111111*x       - we divide both sides of the equation by (1.1111111111111) to get x
100/1.1111111111111=x
90=x
x=90

now we have:
655.29 is 90% of 728.1
