a. - 3 : 6/5 = - 3 x 5/6 = - 15/6 = - 5 /2
b . - 3/6 : 5 = - 3/6 x 1/5 = - 3/30 = - 1 /10
c. - 7/5 : ( 6 + 1 /5) = - 7/5 : ( 30/5 + 1/5 ) = - 7/5 : 31/5 = - 7/5 x 5/31 = - 35/155 = - 7/31
a. 9 : - 5/3 = 9 x - 3/5 = - 27/5
b . 3/5 : 1/5 = 3/5 x 5 = 15/5 = 3
c. - 1/4 : 3 = - 1/4 x 1/3 = - 1/12
d. 22/7 : - 11 = 22/7 x - 1/11 = - 22/77 = - 2 /7
