1. The problem asks to find and highlight fractions on number lines with equal subdivisions between labeled points. 2. a. For $\frac{2}{4}$, the number line between 0 and 1 is divided into 4 equal parts. Point $\frac{2}{4}$ lies exactly at the 2nd division from 0. 3. b. For $\frac{4}{5}$, the number line between 0 and 1 is divided into 5 equal parts. Point $\frac{4}{5}$ lies at the 4th division from 0. 4. c. For $\frac{3}{10}$, the number line between 0 and 1 is divided into 10 equal parts. Point $\frac{3}{10}$ lies at the 3rd division from 0. 5. d. For $\frac{6}{4}$, the number line between 0 and 2 is divided into 8 equal parts with labels at 0, 1, and 2. Since $\frac{6}{4} = 1.5$, it is located 6 divisions from 0 (each division is $\frac{2}{8} = \frac{1}{4}$), lying exactly halfway between 1 and 2. 6. To create similar 20 questions, each should present a fraction and a number line divided accordingly. 7. Each question involves identifying the fraction’s position by counting subdivisions. 8. This exercise helps strengthen fraction understanding and visualization on number lines. Answer summary: a. $\frac{2}{4}$ at division 2 of 4 b. $\frac{4}{5}$ at division 4 of 5 c. $\frac{3}{10}$ at division 3 of 10 d. $\frac{6}{4}$ at division 6 of 8 between 0 and 2
