Question

The electricity received at an electric substation has a potential difference of 2.80 x 10^5 V. If the required output is 440 V, what should be the ratio of the turns of the step-down transformer?

I know the transformer equation is:

Is/Ip = Vp/Vs = Np/Ns

"use that equation to get ratio Np/Ns"
I don't know what numbers to use, I know the numbers in the question but I'm still confused
