In a card game with 84 total cards and a ratio of 4 blue to 3 yellow, how do you find the number of blue cards?

Back

First, add the parts of the ratio: 4 + 3 = 7. Then, divide the total cards by the total parts: 84 ÷ 7 = 12. Finally, multiply the number of blue parts by this result: 4 × 12 = 48 blue cards.
