    Use a proportion.

    A ratio of 44 blue to 33 yellow is the same as a ratio of 4 blue to 3 yellow.

    Since you are told the total of cards, 84, add 3 + 4 = 7

    In the deck, the cards are int he ratio of 4 blue to 3 yellow to 7 total.

    4 blue to 7 total = x blue to 84 total

    4/7 = x/84

    7x = 4 * 84

    x = 4 * 12

    x = 48

    There are 48 blue cards.
