Explicación paso a paso:

-3/7 : 4/12=

-(3 x 12)/(7 x 4)= -36/28= -9/7

41/3 : 22/5 =

(41 x 5)/(3 x 22) = 205/66

15/11 : 4/5 =

(15 x 5)/(11 x 4) = 75/44

17/5 : 4/3 =

(17 x 3)/(5x4) = 51/20

1/2 : 1/3 =

(1 x3)/(2x1) = 3/2

-19/8 x -12/7 =

(-19 x -12)/(8 x 7) = 228/56 = 57/14

(12/5 x 7/4):3/2

(12/5 x 7/4)= 84/20 = 21/5

21/5 : 3/2 = 42/15 = 14/3

(9/8 x 5/4) : (1/4 x 11/3)

(9/8 x 5/4) = 45/32

(1/4 x 11/3) = 11/12

45/32 : 11/12 = 540/352 = 135/88
