Many different possibilities but can narrow down by giving maximum and minimum age limits.
The first member is 39+1 years old.

The second member is 39+2 years old.

The third member is 39+0 years old.

The fourth member is 39-1 years old.

The fifth member is 39-2 years old.

There is more than one possible solutions

Their total ages is 195.
60(father) 60(mother), 30(twins), 30(twins), 15(youngest)

There Is More Than One Possible Explanation

For example, there could be only one elderly parent left, say aged 100 (possible). The eldest child could be 35 years old and the second child could be 25 years old, the third 20 years old, the fourth 15 years old.

There are 5 people in a family and their average age is 39 years....

Too many possibilies.....

A Couple and Their Single Children

this family would consist of:

Father (65 years)
Mother (60 years)
Daughter (30 years)
Son 1 (20 years)
Son 2 (20 years)
(1 Girl and Twin Boys)

Total: 195
Average: 39.
Mother ( 5o years old)
Father ( 55years old)
Triplets(all boys) - 30 years old

Simple Family

Dad and mum= 45 and 42 years old.
Grandfather = 70 year old.
Twins = 19 and 19 years old.
Total age = 39x5=195
There are many possible combination in the family, minium age starts at 1 and max age depends on the oldest in the family.

Let's assume that the 5 members are siblings!

Since the question does not give much details, let's assume they are all siblings of the same family.
The total ages of 5 members is 39 x 5 = 195 , let the eldest brother be 51 years old and there are 2 pairs of twin brothers and twin sisters, each 36 years old. What do you think?
Since the total ages is equal to 195 years, perhaps there is a grandparent who is 80 years old, two parents - 45 & 40 yrs old, two children - 16 & 14 yrs old.

Quintuplets

They are a bunch of quintuplets living together, whose ages are all 39 years.

The ages of the family members

The 5 members in the family are:
- Father (62)
- Mother (61)
- Eldest Son (29)
- Second Son (24)
- Youngest Daughter (19)
For a grand total of 195.

Toh Wee Kwang

Possible answer to Activity 6

Since the total ages is 39 x 5 = 195 years, very likely there is a grandparent who is perhaps 80 yrs old, the 2 parents - 45 & 40 years old and 2 children - 16 & 14 years old.
