Grace baked 4 whole pumpkin pies. She sold 1 whole pumpkin pie and gave 1 whole pumpkin pie to her friend. The remaining whole pumpkin pies were each sliced into 6 pieces. Her family ate 2/3 pieces. How many pieces of pumpkin pie were left?
Grace sold and gave a total of 1 + 1 = <<1+1=2>>2 whole pumpkin pie.
Her family was left with 4 - 2 = <<4-2=2>>2 whole pumpkin pie.
There were a total of 2 x 6 = <<2*6=12>>12 pieces made from the 2 whole pumpkin pie.
Her family ate 12 x 2/3 = <<12*2/3=8>>8 pieces.
Therefore, 12 - 8 = <<12-8=4>>4 pieces of pumpkin pie were left.
