Answer: the elephant is twenty times as heavy as the tiger.
Step-by-step explanation: The weight of an African elephant is 6 × 10^6 grams; the weight of a tiger is 3 × 10^5 grams. How many times heavier is the elephant than the tiger?
2 times
20 times
200 times
2,000 times
The weight of the African elephant is 6 x 10^6 grams = 6,000,000 grams
The weight of the tiger is 3 x 10^5 grams = 300,000 grams
Ratio of the weight of the elephant to that of the tiger is 6,000,000 : 300,000 which on division gives:
= 6,000,000/300,000 = 20.
Therefore the elephant is 20 times as heavy as the tiger.
