Identify whether each of the given structures belongs to the same compound or a different one.

Draw the conformation that results when a chair-chair interconversion is done on each ring of the conformation of a cis-decalin derivative shown here.

True or False. The correct number label is used to show that the chair conformation on the right is the flipped chair of the chair conformation on the left, assuming that the viewing angle of the chair conformation does not change.

For the chair on the left, place the substituents on the flipped chair. Note: The carbon to which the substituent is attached does not change but the axial/equatorial designation changes.
