A baby born at 3.2 kg is expected to follow the rule of tripling the birth weight by 12 months. What weight is expected at one year?
Answer and explanation
Correct answer: B. About 9.6 kg
- Step 1: The rule states that birth weight doubles at about five months and triples at one year. Step 2. 3 x 3.2 kg equals 9.6 kg. Answer: 9.6 kg. Why not the others: 6.4 kg is double, 12.8 kg is four times, and 4.8 kg is 1.5 times the birth weight.
