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
