Can someone please help me with this? 

Im not sure what I’m doing wrong with the units.

Convert the 100 yards to cm (there are 36 inches in a yard). Divide this by the length of the paperclip
1 yd = 36 in
1 in = 2.54 cm
100 yards = 9144 cm
100 yds * 36 in/1 yd * 2.54cm/1 in = 9144 cm
9144 / 3.2 = 2857.5
9144 cm/3.2 cm = 2,857.5 cm

cm/cm should not give you cm
