    Answer: the fraction of the movie that Chad watched at night is 5/12

    Step-by-step explanation:

    Let x represent the fraction of the movie that Chad watched at night.

    Chad watched 1/3 of the movie in the morning and he watch some more at night. This means that the fraction of the movie that Chad watched in the morning and at night is 1/3 + x

    By the end of the day he still had 1/4 of the movie left to watch. Since the entire movie is taken a 1 (whole), it means that

    1/3 + x + 1/4 = 1

    Cross multiplying by 12 (LCM), it becomes

    4 + 12x + 3 = 12

    4 + 3 + 12x = 12

    7 + 12x = 12

    12x = 12 - 7 = 5

    x = 5/12

    5/12

    Step-by-step explanation:

    If the movie equals 1, then subtracting the 1/3 he watched in the morning would give you 2/3 of the movie left. Now take 2/3 and subtract what he has yet to watch and you get 5/12. So chad watched 5/12 of the movie at night.
