Question

add:
1 lb 14 oz + 4 lb 1 oz = □ lb □ oz

Explanation:

Step1: Add pound values

$1\ \text{lb} + 4\ \text{lb} = 5\ \text{lb}$

Step2: Add ounce values

$14\ \text{oz} + 1\ \text{oz} = 15\ \text{oz}$

Step3: Check oz to lb conversion

Since $15 < 16$ (1 lb = 16 oz), no conversion needed.

Step1: Add pound values

$1\ \text{lb} + 4\ \text{lb} = 5\ \text{lb}$

Step2: Add ounce values

$14\ \text{oz} + 1\ \text{oz} = 15\ \text{oz}$

Step3: Verify oz to lb limit

As $15 < 16$, no conversion required.
