Getting the sum of all their ages you'll have:
67(2) + 35(2) + 6(3) = 222
Since they are 7 in the family, then we'll divide the sum with 7
222 ÷ 7 = 31 5/7
Therefore the average age of the family is 31 5/7 yrs.
67(2) + 35(2) + 6(3) = 222
Since they are 7 in the family, then we'll divide the sum with 7
222 ÷ 7 = 31 5/7
Therefore the average age of the family is 31 5/7 yrs.
[tex]You'll \ get \ the \ sum \ of \ their \ ages \ and \ you'll \ get; \\ \\ 67(2)+35(2)+6(3) \\ \\ 134+70+18 \\ \\ The \ sum \ is \ equal \ to \ \boxed{222} \\ \\ Divide \ the \ sum \ by \ 7 \ since \ their \ are \ 7 \ family \ members. \\ \\ \frac{222}{7}=31 \frac{5}{7} \\ \\ Thus, \ the \ average \ age \ of \ the \ certain \ family \ is \ \boxed{31 \frac{5}{7}} [/tex]
