Question

Find the mean of the following numbers a) 1/2,3 b)3/4, 1/3c)-7/2,5/4 d)-8/5,7/9

Answer 1

$We \: know \:that ,$

$\boxed{ \pink{ Mean = \frac{ Sum \: of \: observations }{Number \: of \: observations }}}$

$a) Mean \: of \: \frac{1}{2} \: and \: 3$

$= \frac{ \frac{1}{2} + 3 }{2}$

$= \frac{\frac{1+6}{2}}{2}$

$= \frac{7}{4}$

Therefore.,

$\red{Mean \: of \: \frac{1}{2} \: and \: 3 }$

$\green { = \frac{7}{4} }$

$b) Mean \: of \: \frac{3}{4} \: and \: \frac{1}{3}$

$= \frac{ \frac{3}{4} + \frac{1}{3} }{2}$

$= \frac{\frac{9+4}{2}}{2}$

$= \frac{13}{4}$

Therefore.,

$\red{Mean \: of \: \frac{3}{4} \: and \:\frac{1}{ 3 }}$

$\green { = \frac{13}{4} }$
