Answer:
12 pieces
Step-by-step explanation:
Since on Thursday Glenn and Ben each ate an eight, then total they ate 2*1/8=2/8=¼
¼ of 24 pieces is equivalent to
¼*24=6 pieces
The number of pieces that remain would be 24-6=18 pieces
The one third of leftover ate rhe next day will be equivalent to
⅓ of 18
⅓*18=6 pieces
Remaining pieces next day will be 18-6=12 pieces
Therefore, only 12 pieces out of 24 original pieces remain the following day.
