1) if you divided 20 apples between 'n' numbers of boys, how many apples would each boy get?
2)Put these words into pairs; Ark, Carp, Ling, Mat, Piano, Plaice, Star, Tune.
1) is impossible to answer unless we know what these 'n' numbers are. Or do you mean 'n' boys?
If the latter I seem to remember that one of my many puzzle and recreational maths books makes a distinction between dividing the apples AMONG n boys (in which case they receive 20/n each) and dividing the apples BETWEEN them, in which case the answer is different but I can't remember what! Must find the book if I can.
