Answer:
Number of tadpoles Chris has = 3
Number of tadpoles David has = 6
Number of tadpoles George has = 12
Step-by-step explanation:
Given: Total number of tadpoles divided among 3 friends = 21
Number of tadpoles Mark gave to Chris = A
Number of tadpoles Mark gave to David = B = 2A
Number of tadpoles Mark gave to George = C = 2B = 2(2A) = 4A
∴ Total number of tadpoles = A + B + C
⇒ 21 = A + 2A + 4A
⇒ 21 = 7A
⇒ A = 21 ÷ 7 = 3
∴ Number of tadpoles Chris has = A = 3
Number of tadpoles David has = B = 2A = 2(3) = 6
Number of tadpoles George has = C = 2B = 2(2A) = 4A = 4(3) = 12
