    First convert the mixed number 3 & 3/8 to an improper fraction

    The whole part is w = 3

    The numerator is n = 3

    The denominator is d = 8

    So we'll have the improper fraction (d*w+n) / d = (8*3+3) / 8 = (24+3) / 8 = 27/8

    In other words, the mixed number 3 & 3/8 is equivalent to the improper fraction 27/8

    The whole track is 27/8 feet long. Divide this entire length over the fraction 3/8 to figure out how many poles are needed

    Number of poles needed = (length of entire track) / (distance between poles)

    Number of poles needed = (27/8) divided by (3/8)

    Number of poles needed = (27/8) times (8/3)

    Number of poles needed = (27*8) / (8*3)

    Number of poles needed = 27/3

    Number of poles needed = 9

    Therefore the final answer is 9
