320.5 is what percent of 365 - 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 365 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 365, so we can write it down as 100%=365.
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%=365
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%=365/320.5
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 365

100%/x%=365/320.5
(100/x)*x=(365/320.5)*x       - we multiply both sides of the equation by x
100=1.1388455538222*x       - we divide both sides of the equation by (1.1388455538222) to get x
100/1.1388455538222=x
87.808219178082=x
x=87.808219178082

now we have:
320.5 is 87.808219178082% of 365
