In a pet shop, there are 3 hamsters for every 2 guinea pigs, and there are 2 giant cloud rats for every 3 guinea pigs. If N is the total number of hamsters, guinea pigs, and giant cloud rats, and N > 0, then what is the smallest possible value of N?
We gotta' have 6 guinea pigs to produce "round" numbers....this would mean 9 hamsters and 4 giant cloud rats....so N = 19
