conversations.value: Half the people at the party is 16 / 2 = 8 people.
  8 people at the party eat 1 1/2 rolls each, 8 x 1 1/2 = 12 dinner rolls eaten.
  8 people at the party eat 1/2 a roll each, 8 x 1/2 = 4 dinner rolls eaten.
  Combined, the people at the party ate 12 + 4 = 16 dinner rolls.
  There were originally 40 dinner rolls - 16 that got eaten = 24 dinner rolls leftover.
