Question

Every 5 1/2 cups of flour weighs 1 9/16 pounds. use a unit rate to show how you could determine if there are more than or less than 35 cups of flour in a

10 pound bag of flour

Answer 1

so 5 and 1/2 cup flour =1 and 9/16
multiply both sides by 16
80 and 16/2 cups=16 and 9
88 cups=25 pounds
divide by 5
88/5=5 pounds
multiply by 2
176/5=10 pounds
176/5=35 and 1/5
35 and 1/5 cups=10 pounds

there is MORE than 35 cups of flour in a 10 pound bag
