conversations.value: Let x be the length of the shorter piece.
  The two pieces are 4x and x in length.
  The equation is 4x + x = 40 when the lengths of the two boards are added.
  Adding like terms makes the equation 5x = 40.
  Then dividing 40 by 5 gives the value of x which is 8.
  Since x =8, the longer piece is 4*8 = 32.
