30 kilograms
300 kilograms
3,000 kilograms
30,000 kilograms

Answer 1

To determine how many times one variable to another variable, we get the ratio of both by dividing the values. For this case, we divide the weight of whale and the weight of the elephant.

9 × 10^4 kilograms / 3 × 10^3 kilograms = 30 <------ OPTION 1
