Let's evaluate each proportion one by one:1. To determine if this proportion is true, we can cross-multiply and see if the products are equal. Since the products are equal, the proportion is true.2. Again, we can cross-multiply to check if the products are equal. Since the products are equal, the proportion is true.3. Cross-multiplying, we get: Since the products are not equal, the proportion is false.4. Cross-multiplying, we get: Since the products are equal, the proportion is true.Therefore, the answers are: is True is True is False is True
