Answer 2

Respuesta:

-2/11 + -9/11 = -2-9/11 = -11/11 = -1

17/5 + -19/5 = 17-19/5 = -2/5

-4/6 + 7/8 = -32 +42/48 = 5/24

-5/8 - 11/20 = -25-22/40= -47/40

9/15 - -7/12 = 36+35/60 =71/60

7/5 x -8/6 = -28/15

13/6 x 4/11 = 26/33

-10/8 x -12/20 = 3/4

15/16 x -20/5 = -15/4

20/12 x 25/30 = 25/30

-25/32/10/16 = -5/4

-2/9/8/6= -1/6

(2/3)3= 8/27
