Answer: 4 pounds is equal to 16 four-ounce (1/4 pound) increments.
To find the number of 3/4 pound bags Ann needs to buy, we can convert 16 four-ounce increments to three-fourth pound increments:
16 four-ounce increments = 16 x 4 = 64 ounces
64 ounces = 64/16 = 40 three-fourth pound increments
Therefore, Ann will need to buy 40 bags of walnuts, each weighing 3/4 of a pound.
