First, convert the given percentage to a fraction number, as follow:
325% => 325/100
Next, calculate the previous divisio to identify the remainder:
3.25
100 | 325
-300
250
-200
0500
-500
0
Hence, as you can notice, the whole part of the division is 3 and the remainder is 25/100, which is the same (by simplifcation) that 1/4.
Then, the mixed number is:
3 1/4
