Holly is displaying her pokemon collection on a bulletin board that is 12 1/4 inches wide. Each card is 2 1/2 inches wide. Holly estimates that the number cards she can display in each row is 5. Is this the best estimate? Explain
This would be incorrect. Multiplying how wide the card is (2 1/2) inches by the estimate (5) would equal up to 12 1/2 inches. 12 1/2>12 1/4, so she cannot add the fifth. The correct number would then be 4.
