Explanation:

Step1: Identify interval pattern

Each number line has equal intervals between 0 and the marked fraction, with the next tick being twice the marked fraction.

Step2: Solve Q1: Calculate next fraction

Marked fraction: $\frac{1}{5}$. Next value: $2\times\frac{1}{5}=\frac{2}{5}$

Step3: Solve Q2: Calculate next fraction

Marked fraction: $\frac{1}{3}$. Next value: $2\times\frac{1}{3}=\frac{2}{3}$

Step4: Solve Q3: Note missing marked value

Since the marked fraction after 0 is obscured, we assume the same pattern: if the visible tick was $\frac{1}{n}$, the next is $\frac{2}{n}$. But based on consistency with other problems, we follow the interval rule.

Step5: Solve Q4: Calculate next fraction

Marked fraction: $\frac{1}{7}$. Next value: $2\times\frac{1}{7}=\frac{2}{7}$

Step6: Solve Q5: Calculate next fraction

Marked fraction: $\frac{1}{10}$. Next value: $2\times\frac{1}{10}=\frac{2}{10}$

Answer:

1. $\frac{2}{5}$
2. $\frac{2}{3}$
3. (Note: The marked fraction after 0 is obscured; following the pattern, if the visible tick was $\frac{1}{n}$, the missing fraction is $\frac{2}{n}$)
4. $\frac{2}{7}$
5. $\frac{2}{10}$
