Let the number of pages he has read be x and the number of pages he has not read be 252-x. According to the meaning of the question, the equation could be listed: x × 5/7 = (252 - x) × 2 × 1/2 To simplify it: 5x = 1260 - 7x 8x = 1260 x = 150 Therefore, he had already read 150 pages, and the number of pages he had not read was 252-150=102 pages. Therefore, he had read page 150 but not page 102.
