#30# pieces of pie were sold by noon.

Five pies cut into eighths means there were #5 * 8# or #40# pieces of pie to start the day.

If #3/4# of the piece were sold then this can be represented as #3/4 of 40 => #(3/4)* 40 = > 120/4 => 30#

30 pieces sold by lunchtime.

Each of the 5 pies cut into eighths #-> 5xx8=40# pieces

#3/4xx"pieces" -> 3/(cancel(4)^1)xxcancel(40)^10 =30 # pieces sold
