Question

please give the answer

Answer 1

first convert all the years into months
we get
16 years 4months=16*12+4=196
others are 188,177,183,176
average=196+188+177+183+176/5=920/5=184 months
now convert it into year
184/12=15+4/12 =15 years 4months

Answer 2

$<b >Hey here is your answer$

ages of all 5 girls :-

16 years 4 months
15 years 8 months
14 years 9 months
15 years 3 months
14 years 8 months

average = sum of all of the numbers divided by the number of items

total years and month divided by 5

years are 16 + 15 + 14 + 15 + 14 = 74 years
months are 4 + 8 + 9 + 3 + 8 = 32 months

total number of girls = 5

average = (74 years + 32 months) / 5
= (74 years + 12 months + 20 months) / 5
(74 years + 1 year + 20 months)/ 5
(75 years + 20 months)/5
15 years + 4 months

hope this helps you
