Which of the following numbers does not lie between 4/5 and 7/13 = ?

Answer: Option A

$$\frac{4}{5}$$ = 0.8
$$\frac{7}{13}$$ = 0.53
$$\frac{1}{2}$$ = 0.5
$$\frac{2}{3}$$ = 0.66
$$\frac{3}{4}$$ = 0.75
$$\frac{5}{7}$$ = 0.714
Clearly, 0.5 does not lie between 0.53 and 0.8
∴ $$\frac{1}{2}$$ does not lie between $$\frac{4}{5}$$ and $$\frac{7}{13}$$
