    = 1/4

    Explanation:

    Half life refers to the time taken by a radioactive isotope or atom to decay by half of its original mass.

    Using the formula;

    N = O * (1/2) ^t;

    Where N is the new mass after decay, while O is the original mass of the radioactive isotope before decay, while t is the number of half lives.

    Therefore;

    Number of half lives = 11, 460/5730 = 2 half lives

    Thus;

    New fraction = 1 * (1/2) ²

    = 1/4

    Therefore, the fraction that will remain after decay is 1/4 of carbon-14.
