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 ?
First find the ratios of animals. The ratio of hamsters to guinea pigs to rats is 9:6:4.
This is simplified, so all we have to do is add the values.
9+6+4 is 19.
