A recipe requires 2.5 pounds of flour. If flour is sold only in 16-ounce bags, what is the minimum number of bags needed? (1 pound = 16…

Convert pounds to ounces: $2.5\cdot16=40$ ounces of flour are needed. Each bag holds $16$ ounces, so $\frac{40}{16}=2.5$ bags would be needed, but flour is sold only in whole bags, so round up to $3$ bags, choice G. Two bags hold only $32$ ounces, not enough, which rules out choice F. Choice H ($40$) is the number of ounces, not the number of bags. Choice J ($2.5$) is the exact quotient, but you cannot buy half a bag. When a question asks for the minimum whole number that is enough, round up.
