To step up by means N2/N1 high voltage to low and step down N1/N2.

I agree with 0.13 the 7.5 is k.
Turns ratio = 1/K,
1/7.5 = 0.13.
Turns ratio = 1/K,
1/7.5 = 0.13.

Yes, Agree with the answer 0.13.
Because N2/N1= V2/V1= I1/I2 it is transformation ratio and N1/N2 is Turn Ratio.
Because N2/N1= V2/V1= I1/I2 it is transformation ratio and N1/N2 is Turn Ratio.
