if jan and stan had 2.5 clocks each, then stan got two more. they met jav, who has 100 clocks. what is the averahe amount of clocks?
2.5+2.5+2+100 = 107
between jan, stan and jav makes
$${\frac{{\mathtt{107}}}{{\mathtt{3}}}} = {\mathtt{35.666\: \!666\: \!666\: \!666\: \!666\: \!7}}$$
the have an average of $$35\frac{2}{3}$$ clocks each :)
+4
