Given:
Allie made the line plot below to show the lengths of strings she cut for her art project.
To find:
What is the difference in length between the length of string she used most often and the length of string she used least often?
Solution:
Allie used 12 1/4 inches length of string 2 times.
Allie used 12 1/2 inches length of string 7 times.
Allie used 12 3/4 inches length of string 5 times.
Allie used 13 inches length of string 5 times.
Allie used 13 1/4 inches length of string 4 times.
Therefore, the difference in length between the length of string she used most often and the length of string she used least often = 12 1/2 + 12 3/4 + 13 + 13 1/4 - 12 1/4
= 25/2 + 51/4 + 13 + 53/4 - 49/4
= 25/2 + 55/4 + 13
= (52 + 50 + 55)/4
= 157/4
= 39 1/4 inches.
