Heya
32/5 + 23/4 + 21/5 + 77/10
(32+21)/5 + 23/4 + 77/10
(53×2)/10 + 23/4 + 77/10
(106+77)/10 +23/4
183/10 + 23/4
LCM is 20
(183×2)+(23×5)/20
(366+115)/20
= 481/20
Average = sum of observations/total number of observations
= 481/20 / 4
= 481/80
= 6.0125
Hope it helps! ^_^

Answer:
6 1/8
Step-by-step explanation:
35/5,23/4,21/5,77/10
L.C.M = 20
35/5 × 4 = 128/20. 23/4 × 5 = 115/20
21/5 × 4 = 84/20. 77/10 × 2 = 154/20
= 128/20+115/20+84/20+154/20 = 481/80
Average = sum of observation/number of observation
481/80
= 6.0125
answer in mixed fraction
=6 1/80
