Answer 2

$\underline{ \underline \bold{Given;}} \: \: \: \: \: \dfrac{1}{2}, \: \: \: \: \: \dfrac{5}{6}, \: \: \: \: \dfrac{5}{12}, \: \: \: \: \dfrac{3}{4}$

$\underline{ \underline{\bold{To find : }}} \: \: \: \: \: \: Its \: average$

$\underline{ \underline{ \bold{Solution}}}$

$The \: sum \: of \: the \: number = \\ \: \dfrac{1}{2} + \dfrac{5}{6}+ \dfrac{3}{4} + \dfrac{5}{12} \\ \\ \implies \frac{6 + 5 + 5 + 9}{12} \\ \\ \implies \: \frac{ \cancel{30}} {\cancel{12}}$

$\implies \: \dfrac{10}{4}$

$\bold {now}$

$Mean \: \: of \: \: the \: \: nuumber \: \: = \dfrac{ \frac{10}{4} }{4} \\ \\ \implies \: \frac{10}{4} \times \frac{1}{4} \\ \\ \implies \underline{\bold{\frac{10}{16}\: or \: 0.625}}$
