Question

Justin weighed 8 lb 12 oz when he was born. At his two-week check-up, he had gained 8 ounces. What was his weight in pounds and ounces?

Answer 1

Answer:

9 lb 4 oz

Step-by-step explanation:

Justin weighed 8 lb 12 oz at birth. He gained 8 ounces by his two-week checkup. So,

8 lb 12 oz + 8 oz = 8 lb 20 oz

But, 16 oz equals one pound. So,

20 oz = 1 lb with 4 oz remaining

Now add them together.

8 lb + 1 lb 4 oz = 9 lb 4 oz

Justin's weight is 9 lb 4 oz.

Hope that helps.
