Vector or list to Number "conversion" (SOLVED.)

[Spybot]

Hi Guys!
I'm trying to compare the numeric value of two objects, one is a vector with only one numeric value and the other is a real number; [1/2]==0.5 the Hp Prime returns a zero.

I searched this forum and the UG. for a command that takes the [1/2] out of the brackets so I can compare them, but I found nothing.

this vector [1/2] is the result of solving an equation using the SOLVE command.

what can I do to make the caparison a true statement?

Thank you.
