Every 5 1/2 cups of flour weights 1 9/16 pound. How can I know if there are more than or less than 35 cups of flour in a 10 poun
frez [133]

Answer:More

Step-by-step explanation:

First, you find how much 1 cup of flour weighs. You know 5 1/2cups weighs 1 9/16 so u divide that weight by 5 1/2 to find the weight of per cup.

1 9/16 / 5 1/2

You find that each cup weighs 0.2840909091 pounds.

Then you do 35 multiplied by that number to see how much 35 cups of flour would weigh.

35*0.2840909091=9.9431818185

That means a 10 pound bag of flour would have slightly more than 35 cups.
