Answer:

Q.6

a. 7/9 - 20/9 = -13/9

b. -9/10 - 7/20 = LCM- 20 = -18/20 - 7/20 = -25/20

c. -11/20 - 13/15 = LCM-60 = -33/60 - 52/60 = -85/60

d. 21/25 - 91/100 = LCM- 100 = 84/100 - 91/100 = -7/100

Q.7

a. 12/13 x 2/3 = 24/39

b.  7/20 x (-1/2) = -7/40

c. 3/7 x 0/7 = 0/49

d. 4/19 x (19/-8) = Cancel 19 with 19 and -4 with 8 = -1/2

Q.8

a. (5/11) / (15/22) = 5/11 x 22/15 = Cancel 11 with 22 (you will get 2) and Cancel   5 and 15 (will get 3) = 2/3

b. (25/32) / (65/48) = 25/32 x 48/65 = 35/52

c. (3 1/7) / (11/12) = 22/7 x 12/11 = 24/7

d. (-85/9) / (34/7) = -85/9 x 7/34 = -595/306

I HOPE THIS HELPS YOU OUT!!
