A) Remember that dividing by a/b is the same as multiplying by b/a, except when a or b is zero. To convince yourself of this, note that 4 divided by (2/1) is 4/(2/1) = 4/2 = 2. This is the same as multiplying 4 by (1/2), or 4*(1/2) = 2. So in this case, (-2/5) / (-3/4) is the same as (-2/5)*(4/-3) = (-2*4) / (5*-3) = -8/-15 = 8/15.
B) This division is undefined, since the denominator is zero.
