    The novel has 2160 pages.

    Step-by-step explanation:

    The number of pages of the novel is x.

    Mica has read 1/2 of the novel, so x/2 = 0.5x.

    Denise has read 2/5 of the novel, so 2x/5 = 0.4x.

    Mica has read 216 pages more than Denise

    This means that:

    0.5x - 0.4x = 216

    0.1x = 216

    x = 216/0.1

    x = 2160

    The novel has 2160 pages.
