Question

30

300

3,000

30,000

Answer 1

To find how many times heavier the whale is than the elephant, we need to divide the weight of the whale by the weight of the elephant.

(9 × 10^4 kilograms) / (3 × 10^3 kilograms)

This can be simplified by dividing both numbers by 3:

(3 × (3 × 10^4 kilograms)) / (3 × 10^3 kilograms)

Now we can simplify the expression:

(3 × 10^4 kilograms) / (10^3 kilograms)

Dividing 10^4 by 10^3 gives us 10, so the expression simplifies to:

3 × 10

Which is equal to:

30

Therefore, the whale is 30 times heavier than the elephant. The answer is 30.
