Bob's
kitten weighs 3 pounds. How many ounces is this? |
To
change from a larger unit of length to a smaller unit of
length, multiply. |
3 lbs. =
 ounces |
Since, 1 lb. = 16 oz. |
|
3 x 16 = 48 |
So, 3 lbs. = 48 oz. |
|
Ben's
guinea pig weighs 32 oz. How many pounds is this? |
To
change from a smaller unit of length to a larger unit of
length, divide. |
|
32 oz. =
lbs. |
Since, 16 oz. = 1 lb. |

32 ÷
