Question

june has a 15- pound bag of flour. she used 4.5. she sorted the rest the flour in 2.5-pound portions. What is the maximum number of portions she sorted? How much does she have left that didn't get it into equal portions?

 

Answer 1

15-4.5=10.5lb remaining. 10.5/2.5=105/25=21/5=4.2.

So she could get 4 whole portions of 2.5lb=10lb, leaving ½lb or 0.5lb left over.
