Annmarie wants to make a big batch of cookies for her father. She needs
1 1/4 pounds of chocolate chips, 3/4 pounds of walnuts, and 12 ounces of raisins.
How many ounces of these 3 items does she need in all?
To add pounds and ounces, we need to convert everything to ounces.
1 1/4 pounds = 20 ounces (16 ounces in 1 pound, plus another 4 ounces)
3/4 pounds = 12 ounces (16 ounces in 1 pound, minus 4 ounces)
12 ounces = 12 ounces
Adding them up:
20 ounces + 12 ounces + 12 ounces = 44 ounces
So Annmarie needs a total of 44 ounces of these three items.
