In the final exam, the elder brother's math score was 7 points higher than that of Chinese, and the younger brother's math score was Chinese (6/7). I also know that the younger brother's math score is 4 points higher than the older brother's math score (5/6), and the total score is 3 points lower than the older brother's, so what is the younger brother's Chinese score?
