Answer:
Step-by-step explanation: The second book has 346 pages, the 3rd book has 264 pages. Together they have a total of 346+264 = 610 pages. To find how many pages less is book one than two and 3 combined subtract 137 from the total for books 2 and 3 (610 - 137 = 473). Book 1 is 473 pages less than the other 2 books.
