Answer:
Read 12 pages every night in a chapter book with 144 pages.
Thus the first option is the best because you will use fewer number of days to complete the reading.
Step-by-step explanation:
For the first option;
Read 12 pages every night in a chapter book with 144 pages, the number of days taken to complete the book will be;
144/12= 12 days
For the second option
50 pages = 3 times
132 pages = ? ------perform cross product
(132*3)/ 50 =7.92 ≈ 8 times
3 times = 1 week
8 times = ?
(8*1)/3 = 2.64 weeks
1 week =7 days
2.64 weeks=?
2.64*7 = 18.5 days
Thus the first option is the best because you will use fewer number of days to complete the reading.
