Question

the line plot shows the weights of kittens.
kitten weights
line plot with xs at 3/8, 1/2 (three xs), 5/8 (three xs), 3/4 (one x), 7/8 (one x); x = 1 kitten
what is the difference in weight between the largest and smallest kittens?
a. \\(\frac{1}{2}\\) pound
b. \\(\frac{3}{8}\\) pound

Explanation:

Step1: Identify largest and smallest weights

From the line plot, the smallest weight (leftmost X) is at $\frac{3}{8}$ pound, and the largest weight (rightmost X) is at $\frac{7}{8}$ pound.

Step2: Calculate the difference

Subtract the smallest from the largest: $\frac{7}{8} - \frac{3}{8} = \frac{4}{8} = \frac{1}{2}$ pound. Wait, but wait—wait, rechecking the plot: Wait, the leftmost X is at $\frac{3}{8}$? Wait no, looking at the axis: the first X is at $\frac{3}{8}$? Wait no, the axis marks: 0, $\frac{1}{8}$, $\frac{1}{4}$ (which is $\frac{2}{8}$), $\frac{3}{8}$, $\frac{1}{2}$ ( $\frac{4}{8}$ ), $\frac{5}{8}$, $\frac{3}{4}$ ( $\frac{6}{8}$ ), $\frac{7}{8}$, 1. Wait, the leftmost X is at $\frac{3}{8}$? Wait no, the first X (leftmost) is at $\frac{3}{8}$? Wait the plot: the X's are at $\frac{3}{8}$, $\frac{1}{2}$ (with two X's), $\frac{5}{8}$ (two X's), $\frac{3}{4}$ (one X), $\frac{7}{8}$ (one X)? Wait no, the original plot: let's parse again. The line plot has X's: first at $\frac{3}{8}$, then $\frac{1}{2}$ (two X's), $\frac{5}{8}$ (two X's), $\frac{3}{4}$ (one X), $\frac{7}{8}$ (one X)? Wait no, the user's plot: "X X X" on the top row? Wait maybe I misread. Wait the problem's line plot: the leftmost X is at $\frac{3}{8}$? Wait no, the axis labels: 0, 1/8, 1/4, 3/8, 1/2, 5/8, 3/4, 7/8, 1. The X's: the first X (smallest) is at 3/8? Wait no, maybe the leftmost X is at 3/8, and the rightmost at 7/8. Then difference is 7/8 - 3/8 = 4/8 = 1/2. But wait, the options: A is 1/2, B is 3/8. Wait but wait, maybe I misidentified the smallest. Wait the leftmost X: looking at the plot, the first X (leftmost) is at 3/8? Wait no, the axis: the first mark after 0 is 1/8, then 1/4 (2/8), then 3/8. So the leftmost X is at 3/8, rightmost at 7/8. So 7/8 - 3/8 = 4/8 = 1/2. But wait, the user's selected option is A, but let's confirm. Wait maybe the smallest is 3/8, largest 7/8: 7/8 - 3/8 = 4/8 = 1/2. So the correct answer is A. $\frac{1}{2}$ pound.

Answer:

A. $\frac{1}{2}$ pound
