I can do the problem in my head but I don't know how to explain it to her or to tell her how to show her work. What is the teacher looking for on how to solve this problem? I've tried to read the chapter over and over again and it doesn't make sense to me whatsoever.

**Reiny**, Monday, February 16, 2009 at 11:52pmI also don't quite see how that problem ties in with common factoring, etc.

Unless the teacher is looking for multiples of 5 feet that go into 75

each computer needs 30 inches plus 30 inches to one side, for a total of 60 inches or 5 feet.

So starting with 30 inches on one side of the room we could mark off 5 feet at a time until we reach 25 feet.

so we have 5,10,15,20,25

but that would mean that the first computer would have to be right against the wall.

a rather confusing question for a grade 5
