Miss Peterson is going to install new baseboards in her living room, family room dining room. The total length baseboards needed is 60 yards if Miss Peterson buys 2 2/3 yard long baseboards how many pieces will she need if she buys 3 1/3 yard long baseboards how many pieces will she need?

Answer 1

If Miss Peterson buys 2 2/3 yard long baseboards, she will need 60 yards / (2 2/3 yards) = <<60/(8/3)=22.5>>22.5 pieces.
Since she cannot buy half a piece, she will need to round up to 23 pieces.

If Miss Peterson buys 3 1/3 yard long baseboards, she will need 60 yards / (3 1/3 yards) = <<60/(10/3)=18>>18 pieces. Answer: \boxed{18}.
