`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
```
