solve is returning a list (technically a Sequence). sols[0] is a long expression which will look something like

 t == -1/153680390222338173222270*sqrt((42892173.. etc


You can't turn a relation like this into a number, which is why Sage is complaining. You could extract the rhs:

sage: sols[0].rhs().n()
0.901734601169342 - 1.74583945992054e-17*I


Use solution_dict=True instead (my favourite), i.e.

sols=solve([f(k*t+1-t,l*t,m*t,n*t+1-t)==0], t, solution_dict=True);


and then use [different random numbers here]:

sage: sols[0][t].n()
4.70733338158850 - 5.70444926240249e-18*I
