Answer / guest

Mark would have ate 127/128 (99.22%) of the pizza during the
week.

Mark ate half the pizza on Monday. On Tuesday, he would have
ate half of the remaining pizza i.e. 1/4 of the original
pizza. Similarly, he would have ate 1/8 of the original
pizza on Wednesday and so on for the seven days.

Total pizza Mark ate during the week is

= 1/2 + 1/4 + 1/8 + 1/16 + 1/32 + 1/64 + 1/128

= 127/128

= 99.22% of the original pizza
