Answer 32

Multiply 4/9 by −3. Write the answer as a mixed number in simplest form.(1 point)

$$

Answer 33

[AI-generated answer — Bot GPT 3.5]

To multiply 4/9 by -3, you multiply the numerator (4) by -3 to get -12, and the denominator (9) remains the same. Therefore, the product is -12/9.

To simplify this fraction, you can divide both the numerator and denominator by their greatest common divisor, which is 3.

-12 divided by 3 is -4, and 9 divided by 3 is 3. Therefore, the simplified fraction is -4/3.

In mixed number form, this would be -1 1/3.
