I need help with steps on how to get to the answer

CHAIR . CONFORMATION. S pts 5. (8 pts) (a) In the box labelled (a) below, indicate the number of axial methyl groups when this cyclohexane is in its most stable chair conformation. (b) In the box labelled (b) below, indicate the number of axial methyl groups when this cyclohexane is in its least stable chair conformation (c) In the box labelled (c) below, indicate the number of equatorial ethyl (CH2CH3) groups when this cyclohexane is in its most stable chair conformation. (d) In the box labelled (d) below, indicate the number of equatorial ethyl (CH2CH3) groups when this cyclohexane is in its least stable chair conformation. Ax - Up Methyl Eq - Down b C.
