Points \(A\), \(B\), and \(C\) are marked on the number line.
a) Into how many equal parts is the interval from \(1\) to \(2\) divided? What fraction does one small interval represent?
b) What values are marked by \(A\), \(B\), and \(C\)? Write each as an improper fraction and a mixed number.

Hints
- Count the equal intervals from \(1\) to \(2\).
- Count how many eighths each point lies to the right of \(1\).
- Combine the whole number with the fractional part.
Solution
1. The interval from \(1\) to \(2\) is divided into \(8\) equal parts, so each small interval represents \(\frac{1}{8}\).
2. Point \(A\) is one eighth past \(1\): \(A=\frac{9}{8}=1\frac{1}{8}\).
3. Point \(B\) is five eighths past \(1\): \(B=\frac{13}{8}=1\frac{5}{8}\).
4. Point \(C\) is seven eighths past \(1\): \(C=\frac{15}{8}=1\frac{7}{8}\).
Answer
a) \(8\) equal parts; one interval is \(\frac{1}{8}\)
b) \(A=\frac{9}{8}=1\frac{1}{8}\), \(B=\frac{13}{8}=1\frac{5}{8}\), \(C=\frac{15}{8}=1\frac{7}{8}\)
