Question

A marble rolls 0.7 yards and a penny rolls 0.23 yards. Write a sentence comparing the two distances using a number line to justify the answer.

Answer 1

To compare the distances rolled by the marble and the penny, we can use a number line where each unit represents 0.1 yards. The marble rolls 0.7 yards, which is 7 units on the number line. The penny rolls 0.23 yards, which is 2.3 units on the number line. Therefore, the marble rolls a greater distance compared to the penny.

Step-by-step explanation:

The marble rolls 0.7 yards and the penny rolls 0.23 yards. To compare the two distances, we can use a number line. Let's assign a number line where each unit represents 0.1 yards. For the marble, we can move 7 units to the right (0.7 yards) on the number line. For the penny, we can move 2.3 units to the right (0.23 yards) on the number line. Therefore, the marble rolls a greater distance compared to the penny.
