A) \[\frac{1}{7}\]
B) \[1\frac{1}{7}\]
C) \[1\frac{1}{14}\]
D) \[\frac{2}{7}\]
E) None of these
Correct Answer: A
Solution :
\[?=2+\frac{3}{7}-2-\frac{1}{4}-1-\frac{1}{14}+1+\frac{1}{28}\] \[=(2-2-1+1)+\left( \frac{3}{7}-\frac{1}{4}-\frac{1}{14}+\frac{1}{28} \right)\] \[=\frac{12-7-2+1}{28}=\frac{4}{28}=\frac{1}{7}\]You need to login to perform this action.
