2NO3- is like having nitrogen +10 ( +5*2). On the other hand, N2O3 means you have +6 ( +3*2).

don't u divide nitrogen by 2 in N2O3  -6/2=3

Please, write the reduction reaction as I've, almost, told you. I know you can. :)

10 - 6

How much is it?

Charges aren't balanced. Concentrate on H+: among the reagents there're 6 negative against 2 positive charges.

+ 7 e- ?! Where does this come from?!

You have just to change the number of protons and, consequently, the number of molecules of water. The rest of the chemical equation is correct.
