1 answer
According to the 20% of the total number of pages Su Qian read in the first week, the ratio of the total number of pages he read in the first week was: 20% ÷ 100% = 02 Therefore, Su Qian read 0.2 of the total number of pages in the first week, which was 20%. Next, based on the 30% of the remaining pages that Su Qian read in the second week, the ratio of the total number of pages that he read in the second week was calculated as: 30% ÷ 100% = 03 Therefore, Su Qian read 0.3 of the total number of pages in the second week, which was 30%. Then, the total number of pages left in the novel was: 140 + 02 = 880 Therefore, there were 880 pages left in the novel.
