    It will take him 5 nights to finish the essay.

    Step-by-step explanation:

    Given dа ta:

    Total pages 4

    4/5 is written every night

    Let the total number of nights be X

    (4/5) X = 4

    X = 4 / (4/5)

    X = 4 * 5/4 (invert the fraction)

    X = 20/4

    X = 5 nights

    Answer: it will take 5 nights

    Step-by-step explanation:

    Total number of pages to be written is 4 pages

    If he writes 4/5 page each night

    Assume the number of night be n

    : (4/5) n = 4

    4n/5 = 4

    4n = 4 * 5

    4n = 20

    n = 20/4

    n = 5

    It will take 5 night to finish the essay.

    or

    The remaining part of the essay on each day = 1/5

    Therefore 1/5 * 5 = 5

    It will take five nights to cover up for the remaining part of the pages left on each days.
