Questions: A nurse is converting an infant's weight from lb and oz to kg. The infant weighs 13 lb 8 oz. How many kg does the infant weigh? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Solution Steps

To convert the weight from ounces to pounds, we use the conversion \( 1 \text{ lb} = 16 \text{ oz} \). Therefore, the total weight in pounds is calculated as: \[ \text{total\_pounds} = 13 + \frac{8}{16} \]

Next, we convert the total weight in pounds to kilograms using the conversion \( 1 \text{ lb} = 0.453592 \text{ kg} \): \[ \text{kilograms} = \text{total\_pounds} \times 0.453592 \]

Finally, we round the result to the nearest tenth: \[ \text{kilograms\_rounded} = \text{round}(\text{kilograms}, 1) \]
