A) \[\frac{1}{8}\]
B) \[\frac{2}{7}\]
C) \[\frac{-3}{7}\]
D) \[\frac{-1}{6}\]
Correct Answer: D
Solution :
Arranging the given rational numbers in ascending order, we get \[\frac{-7}{9},\,\frac{-6}{9},\,\frac{-4}{9},\,\frac{1}{9},\frac{5}{9},\frac{8}{9}\]. The two middle rational numbers \[\frac{-4}{9}\]and \[\frac{1}{9}\] Their average is \[\frac{\frac{-4}{9}+\frac{1}{9}}{2}=\frac{-3}{9}\times \frac{1}{2}=\frac{-1}{6}\].You need to login to perform this action.
