Final Answer
At the end of two months, the baby weighs Option (C) 5 3/8 pounds. This sum is derived from adding the weight gained during the first and second monthly visits, totaling 2 6/8 pounds, to the initial weight.
Step-by-step explanation
To find the baby's weight at the end of two months, add the weight gained on the first and second monthly visits. The baby gained 1 2/8 pounds and 1 4/8 pounds, totaling 2 6/8 pounds. Adding this to the initial weight gives 5 3/8 pounds. Therefore, the correct answer is C) 5 3/8 pounds.
This calculation involves converting the fractions to a common denominator and summing the weights gained. It's essential to understand the concept of combining fractions and applying it to real-world scenarios, such as tracking an infant's weight gain over time.
Learning about fraction addition and its practical applications is fundamental not only in mathematical problem-solving but also in fields where measurements and quantities are involved. It's a skill that finds application in various aspects of daily life, from cooking to budgeting.
