65.1 is what percent of 72.8 - 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 72.8 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 72.8, so we can write it down as 100%=72.8.
4. We know, that x% equals 65.1 of the output value, so we can write it down as x%=65.1.
5. Now we have two simple equations:
1) 100%=72.8
2) x%=65.1
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%=72.8/65.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 65.1 is what percent of 72.8

100%/x%=72.8/65.1
(100/x)*x=(72.8/65.1)*x       - we multiply both sides of the equation by x
100=1.1182795698925*x       - we divide both sides of the equation by (1.1182795698925) to get x
100/1.1182795698925=x
89.423076923077=x
x=89.423076923077

now we have:
65.1 is 89.423076923077% of 72.8
