Answer 2

Step-by-step explanation:

a. (-2)*9*(-3) or(-5)*4*(-1)

(-2)*9*(-3)

-2*9=-18

(-18)*(-3)=+54

(-5)*4*(-1)

(-5)*4= (-20)

(-20)*(-1)=+20

54>20

therefore, (-2)*9*(-3) is greater

b. (-5)*2*(-1) or 5*(-2)*1

(-5)*2*(-1)

(-5)*2= -10

(-10)*(-1)= 10

5*(-2)*1

5*(-2)= -10

(-10)*1= -10

10>-10

therefore, (-5)*2*(-1)  is greater
