Answer 1

$\huge\underline\bold {Answer :}$

Pizza he ate on Monday = 1/2

Pizza left = 1/2

Pizza he ate on Tuesday = 1/2 ×1/2 = 1/4

Pizza left = 1/2 – 1/4 = 1/4

Pizza left = 1/2 – 1/4 = 1/4

Pizza he ate on Wednesday = 1/2 × 1/4 = 1/8

Pizza left = 1/4 – 1/8 = 1/8

Continuing this pattern, we see that

Pizza he ate on Thursday, Friday and Saturday and Sunday is 1/16, 1/32, 1/64 and 1/128 respectively.

Therefore, quantity of pizza he ate during the week = 1/2 + 1/4 + 1/8 + 1/16 + 1/32 + 1/64 + 1/128

= 127/128

= 127/128 × 100%

= 99.22%
