Question

a nurse is converting a toddlers weight from lb to kg. if the toddler weighs 17 lb 9 oz, what is the toddlers weight in kg? (round the answer to the nearest whole number. use a leading zero if it applies. do not use a trailing zero.)

Explanation:

Step1: Convert ounces to pounds

Since 1 lb = 16 oz, 9 oz = $\frac{9}{16}$ lb = 0.5625 lb

Step2: Total weight in pounds

17 lb + 0.5625 lb = 17.5625 lb

Step3: Convert pounds to kg

1 lb ≈ 0.453592 kg, so 17.5625 × 0.453592 ≈ 7.966 kg

Step4: Round to nearest whole number

7.966 ≈ 8

Answer:

8
