Help with my math home work please?

There all lots of working that problem the easiest way is you can't exceed 5.75 yards. you start out by adding two blanket 1.85 +1.85 that totals 3.70 then add another blanket of 1.85 to the3.70 so you have added together 3 blankets for a total of 4.55 yards and that's your answer 3 blankets. because if you try to add another blanket of 1.85 to 4.55 you will come up with 6.40 and that will exceed 5.75 yards you have to work with I hope I explained that method easily for you
