$3 \times -1=-3$

As there are $ 2 $ negative numbers in the numerator and $ 1 $ in the denominator, the answer will be negative. 

Cancelling out the common factors and simplifying we get 

As there are $ 3 $ negative numbers, which is an odd number, the product will be negative.

So, $ -5 \times -12 \times 2\times -3 = - 360 $

$4 \times (-3)\times (-2)\times 6\times (-5)$
$=24\times -30$
$=-720$

Given, $

\dfrac { (-60)\times (-72) }{ 36\times (-15) } $

As there are $ 2 $ negative numbers in the numerator and $ 1 $ in the

denominator, the answer will be negative.

Cancelling out the common factors and simplifying we get

$ \dfrac { (-60)\times (-72) }{ 36\times (-15) }=-4\times 2  = - 8 $

As there are $ 4 $ negative numbers, which is an even number, the product

will be positive.





So, $ -5 \times -2 \times -2\times -3 = 60 $

$ (-5)\times 8 = - 40 $

$ 3\times (-2) = -6 $

Hence, $ ((-5)\times 8 ) \times (3\times (-2)) = -40 \times -6 = 240 $

Given, $

\dfrac { (-8) \times 8 \times (-8) \times (-8) }{ (-4)\times (-4) \times (-4) \times (-4) } $

As there are $ 3 $ negative numbers in the numerator and $ 4 $ in the denominator, the answer will be negative.

Canceling out the common factors and simplifying we get

$ \dfrac { (-8) \times 8 \times (-8) \times (-8) }{ (-4)\times (-4) \times (-4) \times (-4) }   =2\times -2\times2\times2 = - 16 $

$(-54)\times (64)\div (-27)\times (-128)$
$=-3456 \div 3456$
$=-1$

$(-144)\div (+16)=\dfrac { -144 }{ 16 } \ =-(\dfrac { 144 }{ 16 } )\ =-(9)$
