    45

    27

    Step-by-step explanation:

    Let the larger number = x

    Let the smaller number = y

    5/3 = x/y

    The numbers differ by 18

    x - y = 18 Add y to both sides

    x = 18 + y Substitute for x in the ratio

    5/3 = (18 + y) / y Cross multiply

    5y = 3 (18 + y) Remove the brackets

    5y = 54 + 3y Subtract 3y from both sides

    5y - 3y = 54 + 3y-3y Combine

    2y = 54 Divide by 2

    2y/2 = 54/2

    y = 27

    The smaller number is 27

    x = y + 18

    x = 27 + 18

    x = 45

    The larger number is 45
