reserve Q,Q1,Q2 for multLoop;
reserve x,y,z,w,u,v for Element of Q;

theorem Th14:
  for f being homomorphic Function of Q1,Q2 holds
  for x,y being Element of Q1 holds f.(x / y) = f.x / f.y
proof
  let f be homomorphic Function of Q1,Q2;
  let x,y be Element of Q1;
  f.(x / y) * f.y = f.((x / y) * y) by Def28b;
  hence thesis;
end;
