42 ounces

In this question, it is asking how many ounces of fiber did the Koala eat that day.

In order to solve this question, we would need to gather some important information from the question.

Important Information:

With the information above, we can solve the question.

We know that koalas only absorb 25% of fiber. We also know that a koala absorbed 10.5 ounces of fiber.

This means that the 10.5 ounces is 25% of fiber. This is 1/4 of the fiber it ate.

Now, we just need to find the other 3/4.

We could just multiply 10.5 by 4 to find how much fiber it ate that day.

When you multiply, you should get 42.

This means that the Koala ate 42 ounces of fiber that day.
