it is the same as multiplying by 0.4
Because multiplying or dividing them by the same NON-ZERO number does not alter their ratio.
Because doing so is equivalent to multiplying or dividing by x/x, which can be cancelled down to 1.
This is related to the fact that dividing by a number is the same as multiplying with the number's reciprocal.
Yes, it is!:)
This is because dividing by a number is the same as multiplying by its reciprocal.

No, taking ½ of a number is the same as dividing it by 2. Dividing a number by ½ is the same as multiplying it by 2.
Dividing by a non-zero rational number is the same as multiplying by its reciprocal.
no, dividing a number is halving it, multiplying iy by 2 is doubling it

That is the definition of reciprocal.
because of mathematical equivalence: it doesn't change the result
