Solve

The line plot shows the height in feet of a number of parade balloons.

Question 1.
What is the difference between the tallest balloon and the shortest balloon shown on the line plot?
4$$\frac{1}{4}$$

Explanation:
The above line plot tells that the tallest balloon is 49$$\frac{3}{4}$$ fee
The shortest balloon is 45$$\frac{2}{4}$$ feet
Subtract to find the difference
49$$\frac{3}{4}$$ – 45$$\frac{2}{4}$$  = 4$$\frac{1}{4}$$ feet
So, the difference between tallest balloon and the shortest balloon shown on the line plot is 4$$\frac{1}{4}$$ feet.

Question 2.
What is the difference of the most common height shown and the shortest height shown?
The above line plot tells that the height of the most common balloon is 47$$\frac{2}{4}$$
The height of the shortest balloon is 45$$\frac{2}{4}$$
47$$\frac{2}{4}$$ – 45$$\frac{2}{4}$$ = 2
