Hey there,
Your question states: 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?
(Tiger)
So we do 3 × 10^5.
10^5 = 100,000
3 × 100,000 = 300,000
(Elephant)
6 × 10^6
10^6 = 1,000,000
6 × 1,000,000 = 6,000,000
_____________________________________________________________
What is greater?
300,000 (or) 1,000,000
1,000,000 is the greatest number.
( it has 7 digits, as for the tiger, weigh's only 6 digit's.
Your correct answer would be D.) 20 grams apart.
Gram's are measured differently, remember!
Hope this helps.
