Let's call the weight of the elephant on Planet B "x". We know that the ratio of the weight on Planet A to the weight on Planet B is 100 to 3, which can be written as:
Weight on Planet A / Weight on Planet B = 100 / 3
We can use this ratio to set up a proportion to solve for "x":
3300 / x = 100 / 3
To solve for "x", we can cross-multiply to get:
3300 * 3 = x * 100
Simplifying the right side, we get:
3300 * 3 = 300x
Dividing both sides by 300, we get:
33 = x
Therefore, the weight of the elephant on Planet B is 33 pounds.
