No
Answer2: Yes.
Scalar S and vector V . S/V= SV*/VV* = SV*/Norm of vector(VV*).
Example: a/bi = a(-bi)/bi(-bi)= -abi/b2 =-ai/b.

A scalar times a vector is a vector.
It is not possible the addition of scalars as well as vectors because vector quantities are magnitude as well as direction and scalar quantities are the only magnitude; they have no directions at all. Addition is possible between scalar to scalar and vector to vector. Under some circumstances, you may be able to treat scalar quantities as being along some previously undefined dimension of a vector quantity, and add them that way. For example, you can treat time as a vector along the t-axis and add it to an xyz position vector in 3-space to come up with a four-dimensional spacetime vector.
Scalar
if you take a vector (= group of numbers) and you divide it by a scalar (=one number) then you get a vector (=group of numbers)
Time is scalar
