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.
