Question: Identify the fractions labeled with the letters A and B on the scale below. Give your answers as proper or improper fractions. A 0 1 B Letter A represents the fraction Letter B represents the fraction Graph: a horizontal number line from 0 to 1 and beyond, with evenly spaced tick marks; A is at the first tick mark to the right of 0 (position_hint=top-left), and B is at the fourth tick mark to the right of 1 (position_hint=center).User: Identify the fractions labeled with the letters A and B on the scale below. Give your answers as proper or improper fractions.

1. **Problem statement:** Identify the fractions at $A$ and $B$ on the number line. 2. **Use the number line rule:** - The interval from $0$ to $1$ is divided into equal parts. - Since $A$ is at the first tick mark to the right of $0$, and there are $5$ equal parts from $0$ to $1$, each tick represents $\frac{1}{5}$. 3. **Find $A$:** - The first tick after $0$ is $\frac{1}{5}$. - So, $A = \frac{1}{5}$. 4. **Find $B$:** - The tick marks continue in steps of $\frac{1}{5}$. - After $1 = \frac{5}{5}$, the fourth tick mark to the right is: $$\frac{5}{5} + \frac{4}{5} = \frac{9}{5}$$ - So, $B = \frac{9}{5}$. 5. **Final answers:** - $A = \frac{1}{5}$ - $B = \frac{9}{5}$
