Mrs. Peterson is going to install new baseboard in her living room, family room, and dining room. The total length of baseboard needed is 60 yards. If Mrs. Peterson buys 223 yard long baseboards, how many pieces will she need? If she buys 313 yard long baseboards, how many pieces will she need?
Responses:
200 pieces; 160 pieces
22 1/2 pieces; 18 pieces
160 pieces; 200 pieces
18 pieces; 22 1/2 pieces
To find the number of pieces Mrs. Peterson will need, we divide the total length of baseboard needed by the length of each baseboard.
If she buys 223 yard long baseboards, she will need 60 yards / 223 yards/piece = 0.269 pieces. Since we cannot have a fraction of a piece, she will need 1 piece.
If she buys 313 yard long baseboards, she will need 60 yards / 313 yards/piece = 0.191 pieces. Again, we cannot have a fraction of a piece, so she will need 1 piece.
Therefore, the correct response is 1 piece for both scenarios.
