Respuesta:

1) 4

2) -6

3) -3

4) -5

5) 21

Explicación paso a paso:

1) [tex]\frac{-28}{((-12+9)-(9-\frac{12}{3})+1)}=\frac{-28}{(-3-(9-4)+1)}=\frac{-28}{(-3-5+1)}=\frac{-28}{-7}=4[/tex]

2) [tex]\frac{-36}{(\frac{-8}{(-5+3)}+\frac{12}{(-2+8)})}=\frac{-36}{(\frac{-8}{-2}+\frac{12}{6})}=\frac{-36}{(4+2)}=\frac{-36}{6}=-6[/tex]

3) [tex]\frac{12}{(-12+8)}=\frac{12}{-4}=-3[/tex]

4) -5(3 - 4) - (6 - 8)(4 - 9) = -5(-1) - (-2)(-5) = 5 - 10 = -5

5) [tex]\frac{-45}{(-2+\frac{12}{(-7+3)})}+12=\frac{-45}{(-2+\frac{12}{-4})}+12=\frac{-45}{(-2-3)}+12=\frac{-45}{-5}+12=9+12=21[/tex]
