Mark $(\checkmark)$ against the correct answer in the following:
$\frac{2}{3},\frac{4}{6},\frac{6}{9},\frac{8}{12}\text{ are}$
Answer$\because\frac{4}{6}=\frac{4\div2}{6\div2}=\frac{2}{3},\frac{6}{9}$
$=\frac{6\div3}{9\div3}=\frac{2}{3}$
and $\frac{8}{12}=\frac{8\div4}{12\div4}=\frac{2}{3}$

Which of the following is correct?
- A
$\frac{2}{3} < \frac{3}{5} < \frac{11}{15}$
- ✓
$\frac{3}{5} < \frac{2}{3} < \frac{11}{15}$
- C
$\frac{11}{15} < \frac{3}{5} < \frac{2}{3}$
- D
$\frac{3}{5} < \frac{11}{15} < \frac{2}{3}$
AnswerCorrect option: B. $\frac{3}{5} < \frac{2}{3} < \frac{11}{15}$
The given fractions are $\frac{2}{3},\frac{3}{5}$ and $=\frac{11}{15}$
$\text{[LCM}$ of $5, 3$ and $15 = 15]$
Now, we have:
$\frac{3}{5}\times\frac{3}{3}=\frac{9}{15},\frac{2\times5}{3\times5}$
$=\frac{10}{15}$ and $\frac{11}{15}$
Clearly,
$\frac{9}{15}<\frac{10}{15}<\frac{11}{15}$
$\therefore\frac{3}{5}<\frac{2}{3}<\frac{11}{15}$

- ✓
$\frac{9}{16}>\frac{13}{24}$
- D
AnswerCorrect option: C. $\frac{9}{16}>\frac{13}{24}$
$\frac{9}{16}=\frac{13}{24}$
$\Rightarrow9\times24<13\times16$
$\Rightarrow216=208,$ which is not true.
$\frac{9}{16}<\frac{13}{24}$
$\Rightarrow9\times24>13\times16$
$\Rightarrow216>208$ Which is true.
