✔ 最佳答案
Assuming that Janet finished 0.14 of a story book each day for the rest of the week.At the end of one week, Janet finished 0.14X7 = 0.98
The fraction of the book left unread =
= 1 - 98
100
= 2
100
= 1_
50

One day of reading covers 0.14.
1 week of reading covers 0.14 x 7 = 0.98
Fraction left unread = 1 - 0.98 = 0.02
1 week of reading covers 0.14 x 7 = 0.98
Fraction left unread = 1 - 0.98 = 0.02

Janet 一日只睇了 0.14 (即14%) 的書, 即還有 0.86 (86%) 未睇.
一個星期有七日, 但第一日已睇了 14%, 假設她其餘日子不再睇, 即 0.86*6 = 5.16

參考: 我教英文, 但唔係數學, 希望我既答案係o岩
