A story book has 120 pages. Xiao Ming read 16 of the whole book on the first day and the remaining 14 on the second day. How many pages are left?
There are still 75 pages left after Xiao Ming's first day reading: 120-120 × 16 = 120-20 = 100 (pages) 100-100 × 14 = 100-25 = 75 (pages)
Wang Qiang read a story book. He read 1 / 3 of the whole book on the first day and 1 / 4 of the whole book on the second day. There are 60 pages left to read. How many pages are there in this story book?
60 ÷ (1-1 / 3-1 / 4) = 144 pages
The story book has 144 pages

(the explanation should be more detailed, and the equation process should also be written when the equations are listed.)
