Lily’s mother asks Lily to buy 4 pounds of flour from the grocery store. The weights on the flour packages are in ounces. The ratio of pounds to ounces is 1 : 16. What is the amount of flour in ounces that Lily needs to buy?

Answer 2

let's think about what the ratio means

pounds to ounces = 1 : 16
this means 1 lb = 16 oz

so to convert lbs to oz, simply multiply your amt. in pounds, by 16, to get oz.
