Answer: 27 times greater.
Explanation:
First convert the weight of Randy's cat to kilograms so you can compare the weights more easily. There are 1000 grams in a kilogram, so to convert 5000 grams to kilograms, divide by 1000. 5000/1000=5. Randy's cat weighs 5 kg.
To find out how many times greater the mass of a tiger is, divide the mass of the tiger by the mass of Randy's cat. 135/5=27. This means the tiger's mass is 27 times greater than that of Randy's cat.
