Hartley has 4 puppies that each weigh 7.5 kilograms. The rescue center has 14 cats that each weigh 2.5 kilograms. How many kilograms more do the cats weigh than the puppies? Let's be accurate as possible.

Puppies = 4 * 7.5 = 30 kg. Cats = 14 * 2.5 = 35 kg. 35 - 30 = 5. The cats weigh 5 kg more than the puppies.
The answer: 5.
