    Answer:  24

    Explanation:

    x = smaller number

    8x = larger number, since it’s 8 times larger than the smaller

    8x-x = 7x = difference of the numbers

    That difference is 21, so we can say 7x = 21 which solves to x = 3

    The smaller number is 3 and the larger is 8x = 8*3 = 24

    As a check: 24-3 = 21, which confirms the answer.
