Question

find the mean of1/3, 3/4, 5/6, 1/12, 7/12​

Answer 1

Step-by-step explanation:

$mean = \frac{sum \: of \: all \: observations}{total \: number \: of \: observations \: }$

$mean \: = \frac{ \frac{1}{3} + \frac{3}{4} + \frac{5}{6} + \frac{1}{12} + \frac{7}{12} }{5}$

$mean = \frac{ \frac{4}{12} + \frac{9}{12} + \frac{10}{12} + \frac{1}{12} + \frac{7}{12} }{5}$

$mean = \frac{31}{12 \times 5}$

$= \frac{31}{60}$
