Question

Janine has 10 pieces of ribbon. She recorded the length of each piece in the line plot below. What is the total length of the four longest pieces of ribbon?

Answer 1

51 1/4 centimeters

Explanation:

According to the line plot, the 4 longest pieces of ribbon are :

• 13, 12 3/4, 12 3/4, and 12 3/4

Total length = Sum of the 4 pieces

• 13 + 12 3/4 + 12 3/4 + 12 3/4
• 25 3/4 + 25 2/4
• 51 1/4 centimeters

Answer 2

51.25

Explanation:

The four longest pieces are the four X’s on the farthest right.

These X’s have values of 12.75, 12.75, 12.75, and 13.

12.75 + 12.75 + 12.75 + 13

25.5 + 12.75 + 13

38.25 + 13

51.25

Therefore, my answer is correct.
