(1) 72 = 49 82 = 64 92 = 81 So, the number of perfect square between 50 and 65 is 1 i e 64 (2) If one pair of opposite side of a quadrilateral is parallel, then it is a trapezium (3) The additive inverse of $\frac{3}{7}$ is $\frac{- 3}{7}$ (4) Rational number between $\frac{2}{3}$ and $\frac{4}{3}$ is $\frac{\frac{2}{3} + \frac{4}{3}}{2}$ = $\frac{6}{6}$ = 1 Rational number between $\frac{2}{3}$ and 1 is $\frac{\frac{2}{3} + 1}{2}$ = $\frac{5}{6}$ Rational number between 1 and $\frac{4}{3}$ is $\frac{1 + \frac{4}{3}}{2}$ = $\frac{7}{6}$ Thus required rational numbers are $\frac{5}{6}$ , 1, $\frac{7}{6}$ Due to paucity of time it would not be possible for us to provide the answers to all your queries We are providing solutions to some your good queries Try solving rest of the questions yourself and if you face any difficulty then do get back to us
