A line plot is a graph that records each piece of data on a number line.

**Step It Out**

Question 1.

The weights of some cellphones and tablets are shown. How can you display the data using a line plot?

A. Order the data from least to greatest.

Answer:

The weights of some cellphones and tablets data are given in pounds.

The given data are 3/4, 1 3/8, 1 1/2, 3/8, 1/4, 1/4.

The mixed fraction 1 3/8 in fraction form as **11/8**.

The mixed fraction 1 1/2 in fraction form as **3/2**.

The given data from least to greatest are **1/4, 1/4, 3/8, 3/4, 1 3/8, 1 1/2**.

B. Complete the tally table.

Answer:

C. To determine the intervals, look at the fractions and determine which common denominator you could use. Which interval would you use to make the number line?

Answer:

We can use common denominator as 8. The interval used to make the number line is 1/8.

D. Label the fraction lengths on the number line. Plot an X for each data point. Write a title, and label the units used.

Answer:

Question 2.

The line plot shows the widths of different portable music players. How much greater is the width of the widest portable music player than the narrowest?

A. Draw a box around the value that shows the width of the narrowest portable music player. Draw a circle around the value for the widest.

Answer:

B. Determine which operation to use to find the answer. Write an equation and solve.

Answer:

The operation I used to find the answer is subtraction.

The mixed fraction of 1 1/8 is 9/8.

The equation is 1 1/8 – 1/4

9/8 – 1/4 = **7/8**

C. The widest portable music player is inches wider than the narrowest.

Answer:

The widest portable music is 9/8.

The narrowest portable music is 1/4.

9/8 – 1/4 = **7/8**

The widest portable music player is 7/8 inches wider than the narrowest.

**Turn and Talk** How does knowing equivalent fractions help you make a line plot?

Answer:

**Check Understanding**

Question 1.

The thicknesses of different e-readers are shown.

\(\frac{3}{8}\) in., \(\frac{3}{4}\) in., \(\frac{3}{8}\) in., \(\frac{3}{8}\) in., \(\frac{3}{8}\) in., \(\frac{1}{4}\) in.,

Show the data on a line plot.

Answer:

Question 2.

Suppose all the e-readers were stacked on top of each other. What would the thickness of the stack of e-readers be?

Answer:

The thicknesses of different e-readers are in inches 3/8, 3/4, 3/8, 3/8, 3/8, 1/4.

The e-readers were stacked on top of each other.

3/8 + 3/4 + 3/8 + 3/8 + 3/8 + 1/4 = 20/8 inches

The thickness of the stack of e-readers be **20/8 or 5/2 inches**.

**On Your Own**

Question 3.

Model with Mathematics Erik measures how much six plants grow in two weeks. Make a line plot to display the data. Include a title and label the units.

Answer:

Question 4.

The data show the different weights of some AA and AAA batteries. Complete the tally table, and make a line plot to represent the data.

\(\frac{3}{8}\) oz, \(\frac{5}{8}\) oz, \(\frac{7}{8}\) oz, \(\frac{5}{8}\) oz, \(\frac{3}{8}\) oz, \(\frac{5}{8}\) oz

Answer:

Question 5.

The line plot shows the distances Sara walks at different times of the day according to her pedometer.

How far does Sara walk during the day?

Answer:

1/8 + 1/8 + 2/8 + 5/8 + 8/8 = **17/8 miles**

Sara walk 17/8 miles during the day.

Question 6.

**Attend to Precision** Use the tally table to make a line plot to represent the data.

Answer:

Question 7.

**Use Tools** A wildlife center records the weights of six reptiles. The fractions represent the weights, in pounds, of the reptiles. Make a line plot to display the data. What is the difference in weight between the heaviest and lightest reptiles weighed?

\(\frac{5}{8}\), \(\frac{9}{8}\), \(\frac{5}{8}\), \(\frac{7}{8}\), \(\frac{7}{8}\), \(\frac{8}{8}\)

Answer:

The weight of the heaviest reptile is 9/8 pounds.

The weight of the lightest reptile is 5/8 pounds.

9/8 – 5/8 = 4/8 pounds

The difference between the heaviest and lightest reptiles weighed is 4/8 pounds.

Question 8.

**Open Ended** Why might you use a line plot to display data? Give an example of a situation where you would use a line plot, and explain why.

Answer:

Using line plot to display data gives us clear picture of the measurement of how much units the object is and also easily comparable with other objects.
