Question

Find the mean of 1/3 3/4 5/6 1/12 7/12

Answer 1

$mean = \frac{31}{60}$

Step-by-step explanation:

$mean = \frac{sum \: of \: all \: observations}{total \: number \: of \: observations} \\ mean = \frac{ \frac{1}{3} + \frac{3}{4} + \frac{5}{6} + \frac{1}{12} + \frac{7}{12}}{5} \\ mean = \frac{ \frac{4}{12} + \frac{9}{12} + \frac{10}{12} + \frac{1}{12} + \frac{7}{12} }{5} \\ mean = \frac{31}{12 \times 5} \\ mean = \frac{31}{60}$
