I know the missing bit of information to answer this question: There are 16 ounces in a pound. So we're multiplying everything by 16 to convert pounds to ounces.
a)
3/4 pounds × 16 ounces/pound = 12 ounces
b)
5/8 pounds × 16 ounces/pound = 10 ounces
c)
12 ounces - 10 ounces = 2 ounces
d)
Winn Fruit total
W = 12 + 10 = 22 ounces
Phillips Fruit total
P = 1 3/4 pounds × 16 ounces/pound = 16(7/4) = 28 ounces
Answer: Mr. Phillips bought 6 ounces more than Ms. Winn
