Answer:

Explanation:

1).
((-4)/(9))* ((7)/(4))=(-1)((4)/(9))((7)/(4) )


=-(7)/(9) [Negative]

2).
(-2(3)/(4))(-1(1)/(5))=(-1)(2(3)/(4))(-1)(1(1)/(5))


=(-1)^2(2(3)/(4))(1(1)/(5))


=(2(3)/(4))(1(1)/(5)) [Positive]

3). (3)(-3)(-3)(-3)(-3) = 3.(-1).3.(-1).3.(-1).3(-1).(3)

= (-1)⁴(3)⁵

= (3)⁵ [Positive]

4).
(-(1)/(6))(-2)(-(3)/(5))(-9) =
(-1)((1)/(6))(-1)(2)(-1)((3)/(5))(-1)(9)

=
(-1)^4((1)/(6))(2)((3)/(5))(9)

=
((1)/(6))(2)((3)/(5))(9) [Positive]

5).
(-(4)/(7))(-(3)/(5))(-9)=(-1)((4)/(7))(-1)((3)/(5))(-1)(9)


=(-1)^3((4)/(7))((3)/(5))(9)


=-((4)/(7))((3)/(5))(9) [Negative]

6).
(-(10)/(7))((8)/(3))=(-1)((10)/(7))((8)/(3))


=-((10)/(7))((8)/(3)) [Negative]
