A package weighs 1 lb 5 oz. How many ounces does it weigh?

21 ounces

Step-by-step explanation:

You need to know that 1 lb is equal to 16 oz.

Replace 1 lb with 16 oz

1 lb 5 oz

16 oz + 5 oz

21 oz

21 ounces

Step-by-step explanation: First of all, we need to start with the conversion factor for pounds and ounces which is 16 ounces = 1 pound.

So since we're given that the package weighs 1 pound and 5 ounces, we can rewrite the problem to say the package weighs 16 ounces and 5 ounces. I put 16 since the conversion factor for pounds and ounces.

Now we can add 16 and 5 together to get a sum of 21.

This means that the package weighs 21 ounces.
