    David gets 28 more than Dan

    Step-by-step explanation:

    Jim: Dan : David: total

    3 : 1 : 5 : 3+1+5 = 9

    Jim gets 21

    21/3 = 7

    Multiply each number by 7

    Jim: Dan : David: total

    3*7 : 1*7 : 5 * 7 : 9*7

    21 : 7 : 35 : 63

    David has 35 and Dan has 7

    35-7 = 28

    David gets 28 more than Dan
