Respuesta:

Explicación paso a paso:a.) -2/11 + (-9/11) 

= -2/11 - 9/11

= -11/11

= -1

b.)17/5 + (-19/5)

= 17/5 - 19/5

= -2/5

= -0.4

c.)-4/6 + 7/8

= (-32+21)/24

= -11/24

=0.46

d.) -5/8 - 11/20

= (-25-22)/40

= -47/40

=-1.175

e.) 9/15 - (-7/12)

= (36+35)/60

= 71/60

=1.18

f.)7/5 * (-8/6)

= -56/30

= -28/15

=-1.86

g.) 13/6 * 4/11

= 52/66

= 26/33

= 0.7878

h.) -10/8 * (-12/20)

= 120/160

= 3/4

=0.75

i.) 15/16 * (-20/5)

= -300/80

= -15/4

= -3.75

j.) (20/12) / (25/30)

= 600/300

= 2

k.) (-25/32) / (10/16)

= -400/320

= -5/4

= -1.25

l.) (-2/9) / 8/6)

= -12/72

= -1/6

= -0.16666

m.) (2/3)³

= 2³ / 3³

= 8/27

= 0.296

n.)  ( se simplifican)

= 9²

=81
