4. The novels on Suzanne’s bookshelf have a combined total of 672 pages. If each novel has 4 chapters and there are 6 pages per chapter, how many novels are there altogether?
If each novel has 4 chapters and there are 6 pages per chapter, then each novel has a total of 4*6 = <<4*6=24>>24 pages.
If the total number of pages on Suzanne's bookshelf is 672, then the number of novels is 672/24= <<672/24=28>>28. Answer: \boxed{28}.
