Answer:
25 inches
Explanation:
If each eraser is 2 ½ inches long, and you have 10 erasers placed end to end, you can calculate the total length by multiplying the length of one eraser by the number of erasers.
Length of one eraser: 2 ½ inches = 2.5 inches
Number of erasers: 10
Total length of 10 erasers: 2.5 inches * 10 = 25 inches
Therefore, 10 erasers placed end to end would have a total length of 25 inches.
