Question

Allie made the line plot below to show the lengths of strings she cut for her art project. What is the difference in length between the length of string she used most often and the length of string she used least often? Line plot named as ALTDCLength of StringsALTDC shows a number line from 12 to thirteen and one-fourth. The number line is divided into 5 equal parts. 2 dots on twelve and one-fourth, 7 dots on twelve and half, 5 dots on twelve and three-fourths, 5 dots on 13 and 4 dots on thirteen and one-fourth is given. A. 1 inch B. 18inch C. 14inch D. 114inches

Answer 1

Answer:

(C)$\dfrac{1}{4} inch$

Step-by-step explanation:

On the dot plot there are:

• 2 dots on twelve and one-fourth,
• 7 dots on twelve and half,
• 5 dots on twelve and three-fourths,
• 5 dots on 13 and
• 4 dots on thirteen and one-fourth is given.

Length of String Used Most = twelve and half

Length of String Used Least = twelve and one-fourth

Therefore, the difference in Length

$=12\dfrac{1}{2}- 12\dfrac{1}{4}\\\\=(12+\dfrac{1}{2})- (12+\dfrac{1}{4})\\=\dfrac{1}{2}-\dfrac{1}{4}\\\\=\dfrac{1}{4} inch$

The correct option is C.
