Welcome on board! As an expert in habitat design, use area models to show what fraction of each habitat is dedicated to the enrichment area. Check out the example for the penguin exhibit, then find the answers for the polar bear, otter, and hippo exhibits.

Area models are a handy tool for solving multiplication problems, even with fractions. Here's how you'll do it for 1/2 x 3/4: Start by dividing the area model vertically into two equal parts and shade one to represent 1/2. Then, divide the same area model horizontally into four equal parts and shade three to represent 3/4. Count the total number of sections in the area model and how many are shaded twice to find your answer: 3/8. Now, use this method to complete the challenge.
