Equivalent resistance in circuits

Homework Statement

The top two resistors are in parallel, so their equivalent resistance is 0.6 ohms.

But if you were to draw the equivalent circuit, where do we place this equivalent resistance?
can it be placed either where the 1 ohm or 2 ohm resistors used to be?
would it affect my answer for the equivalent resistance of the whole circuit?

Don't forget about the "k"!

The two parallel resistors are attached to two distinct nodes. The equivalent resistance of those two resistors will be attached to the same two nodes.

would it affect my answer for the equivalent resistance of the whole circuit?

No.
