Question

find the mean of the following numbers
$1 \2 + 3 \\3 \4 + 1 \3 \\ - 7 \2 + 5 \4 \\ - 8 \5 + 7 \9$
​

Answer 1

${\bold{\green{\sf{→\frac{1}{2}+3=\frac{1+6}{2}=\frac{7}{2}}}}}$

${\bold{\red{\sf{→\frac{3}{4}+\frac{1}{3}=\frac{9+4}{12}=\frac{13}{12}}}}}$

${\bold{\green{\sf{→\frac{-7}{2}+\frac{5}{4}=\frac{5-14}{4}=\frac{-9}{4}}}}}$

${\bold{\red{\sf{→\frac{-8}{5}+\frac{7}{9}=\frac{35-72}{45}=\frac{37}{45}}}}}$

Answer 2

3 + 1 + 3 + 1 + 7 + 5 + 8 + 7/8
=35/8


Or



3+1/2
=4/2
=2

7+5/2
=13/2

8+7/2
=15/2
