A baby weighs 7 lb 4 oz at birth. Calculate the baby's weight in kg : \( \square \) kg Round to two decimal places

1. Convert the ounces to pounds. Since there are 16 oz in 1 lb, we have: \[ 4\,\text{oz} = \frac{4}{16} = 0.25\,\text{lb} \] 2. Add this to the pounds: \[ 7\,\text{lb} + 0.25\,\text{lb} = 7.25\,\text{lb} \] 3. Convert pounds to kilograms using the conversion factor \(1\,\text{lb} = 0.45359237\,\text{kg}\): \[ 7.25\,\text{lb} \times 0.45359237\,\text{kg/lb} \approx 3.29\,\text{kg} \] Thus, the baby's weight is \(3.29\) kg.
