as 9 is made of 3 times 3
so any number (such as 90) which is divisible
by 9 will also be divisible by 3 and the
answer will be 3 times bigger
so 90/9 is 10 then 90/3 = 30 which is 10 x 3
Example: same for any number that is divisible by 14 will
also be divisible by 7 (or also 2) as 14 = 7 x 2
or divisible by say 50 is also divisible by 5 or 10 as 50 = 5 x 10
and so on ...
