Tina had three days to finish a book of 100 pages. She finished 44 pages on the first day, 32 pages on the second day, and 18 pages on the third day. Did she finish the book in time?
Number of pages finished on the first day = 44 pages
Number of pages finished on the second day = 32 pages
Number of pages finished on the third day = 18 pages
Total number of pages finished = 44 + 32 + 18
Using the property of addition, we get:
44 + (32 + 18)
= 44 + 50
= 94
Hence, 94 pages are finished in three days. So, the work is not finished completely as she needed to finish 100 pages.
