If the ratio A:B is 3:4 and B = 8, what is A?

Understanding ratios means comparing two quantities by equal parts. A:B = 3:4 means A is 3 parts for every 4 parts B has. If B equals 8 and B corresponds to 4 parts, each part is 8 ÷ 4 = 2. A has 3 parts, so A = 3 × 2 = 6. The ratio then is 6:8, which simplifies to 3:4, matching the given relationship. Therefore, A is 6.
