    5/8 - 3/10

    Find the common denominator:

    Multiples of 8: 8, 16, 24, 32, 40 (8 x 5 = 40)

    Multiples of 10: 10, 20, 30, 40 (10 x 4 = 40)

    5/8 = 5*5 / 8*5 = 25/40

    3/10 = 3*4 / 10 * 4 = 12/40

    Now you have 25/40 - 12/40

    25 - 12 = 13

    Answer = 13/40

    The answer is A.
