To find the difference in length between the longest and shortest pieces of ribbon in the line plot, we first identify the longest and shortest lengths represented in the plot:
- The shortest length is 1 and 3/4 yards (1.75 yards).
- The longest length is 4 and 2/4 yards (4.5 yards).
Next, we calculate the difference:
4.5 yards - 1.75 yards = 4.5 - 1.75 = 2.75 yards.
The difference in length between the longest and shortest pieces of ribbon is 2 3/4 yards.
