Reasoning & answer: CoT: If there are 15 people in the house, the number of people eating pizza is 3 / 5 * 15 = 9 people. If each house member who eats pizza took four pieces to eat, the number of pieces taken is 4 * 9 = 36 pieces. Since the total number of pieces was 50, the number of pieces not taken is 50 - 36 = 14 pieces.
The answer: 14
