I agree @Rajkumar.
Second thing is that they can never be fractional it is always integral.

The answer is wrong. "Transformation ratio" and "turns ratio" are one and the same thing, the formula is N1/N2 = V1/V2 = I2/I1.
The answer is k = 400/2000 = 0.2.
The answer is k = 400/2000 = 0.2.

Actually, the turns ratio means n1/n2 so 400/2000=0.2.
The ans 5 i.e 2000/400 for transformation ratio=n2/n1.
The ans 5 i.e 2000/400 for transformation ratio=n2/n1.

The answer is n1/n2 i.e 0.2.

The turns ratio=n1/n2.
400/2000=0.2.
400/2000=0.2.

Answer is 0.2.
Turns ratio is n1/n2.
Transformation ratio is n2/n1.
Turns ratio is n1/n2.
Transformation ratio is n2/n1.

Turns ratio N1/N2 & transformation ratio N2/N1.

Turn Ratio:
It is defined as the ratio of primary to secondary turns.
TR= N1/N2.
and
Transformation Ratio
The transformation ratio is defined as the ratio of the secondary voltage(or turns) to the primary voltage(or turns). It is denoted by K.
K= (E2/E1) or (N2/N1) or (I1/I2).

Turns ratio.
I think n1/n2 because transformation ratio is n2/n1 once you cross I agree @Jyothi.
