320.5 is what percent of 320 - 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 320 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 320, so we can write it down as 100%=320.
4. We know, that x% equals 320.5 of the output value, so we can write it down as x%=320.5.
5. Now we have two simple equations:
1) 100%=320
2) x%=320.5
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%=320/320.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 320.5 is what percent of 320

100%/x%=320/320.5
(100/x)*x=(320/320.5)*x       - we multiply both sides of the equation by x
100=0.9984399375975*x       - we divide both sides of the equation by (0.9984399375975) to get x
100/0.9984399375975=x
100.15625=x
x=100.15625

now we have:
320.5 is 100.15625% of 320
