-8/7 ÷ 6/5 = -20/21
-2/5 ÷ 7/10 = -4/7
7
(-7/12) / (-3/4) = (7/12) / (3/4) = (7/12) * (4/3) = (7/3)*(1/3) = 7/9
(-2/7) / (-4/49) = (-2/7) * (-49/4) = 98/28 = 3.5
96
it would be 10/7
-17/7 ÷ -51/7 = 1/3
-36 ÷ -7/8 = -288/-7 = 288/7 or 411/7
-8/7 ÷ 6/5 = -20/21
-2/5 ÷ 7/10 = -4/7
7
(-7/12) / (-3/4) = (7/12) / (3/4) = (7/12) * (4/3) = (7/3)*(1/3) = 7/9
0.8571
(-2/7) / (-4/49) = (-2/7) * (-49/4) = 98/28 = 3.5
