A) \[\frac{5}{7}<\frac{7}{9}<\frac{9}{11}<\frac{11}{13}\]
B) \[\frac{11}{13}<\frac{9}{11}<\frac{7}{9}<\frac{5}{7}\]
C) \[\frac{5}{7}<\frac{11}{13}<\frac{7}{9}<\frac{9}{11}\]
D) Both (b) & (c)
Correct Answer: D
Solution :
\[\frac{5}{7}=0.71\,;\] \[\frac{7}{9}=0.77\] \[\frac{9}{11}=0.81\,\,;\] \[\frac{11}{13}=0.84\] So, \[\frac{5}{7}<\frac{7}{9}<\frac{9}{11}<\frac{11}{13}.\] Hence, both (b) and (c) are false.
