Question

a nurse is converting a toddlers weight from lb to kg. if the toddler weighs 20 lb 8 oz, what is the toddlers weight in kg? (round the answer to the nearest tenth. use a leading zero if it applies. do not use a trailing zero.)

Explanation:

Step1: Convert ounces to pounds

Since 1 lb = 16 oz, 8 oz = $\frac{8}{16}$ lb = 0.5 lb.

Step2: Total weight in pounds

Total weight = 20 lb + 0.5 lb = 20.5 lb.

Step3: Convert pounds to kg

1 lb ≈ 0.453592 kg, so weight in kg = 20.5 × 0.453592 ≈ 9.3 kg.

Answer:

9.3
