321.28 is what percent of 360 - 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 360 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 360, so we can write it down as 100%=360.
4. We know, that x% equals 321.28 of the output value, so we can write it down as x%=321.28.
5. Now we have two simple equations:
1) 100%=360
2) x%=321.28
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%=360/321.28
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 321.28 is what percent of 360

100%/x%=360/321.28
(100/x)*x=(360/321.28)*x       - we multiply both sides of the equation by x
100=1.1205179282869*x       - we divide both sides of the equation by (1.1205179282869) to get x
100/1.1205179282869=x
89.244444444444=x
x=89.244444444444

now we have:
321.28 is 89.244444444444% of 360
