Answer:

  5/12

Step-by-step explanation:

Since Pedro had 1/3 of the book remaining at the end of the day, he had read a total of 2/3 of the book. If n represents the amount read at night, you have ...

  1/4 + n = 2/3

  3 +12n = 8 . . . . . multiply by 12

  12n = 5 . . . . . . . .subtract 3

  n = 5/12 . . . . . .  divide by 12

Pedro read 5/12 of the book at night.

_____

Since Pedro reads only a fraction of the book, it is not a "mixed number."

__

The solution is equivalent to finding the difference ...

  2/3 - 1/4

  = 8/12 - 3/12 = 5/12
