Answer 1

Answer:

  28/81

Step-by-step explanation:

As you know, the product of fractions is the product of their numerators, divided by the product of their denominators. As with any product, the sign will be positive if there are an even number of minus signs among the factors.

  (-4/9)(-7/9) = (4·7)/(9·9) = 28/81
