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: $2\times\frac{1}{10}=\frac{2}{10}$
