How many times larger is a 10-pound dog than a hamster weighing 5/8 pound?

To determine how many times larger is a 10-pound dog compared to a 5/8-pound hamster, we divide the mass of the dog by the mass of the hamster. This is as shown below,
               n = mass of the dog / mass of the hamster

Substituting the known value,
              n = 10 lb/ 5/8 lb
              n = 16

ANSWER: 16 times

Ithink it's the first one ( let me know if it right)
