Mathematics problem: in the subject collection of the school library, Chinese books and foreign language books account for about 1 / 5, mathematics books account for about 1 / 10, history, geography and students books account for about 1 / 6, and the rest of the books are classified into other categories. According to these data, draw a fan statistical chart of the subject collection of the school library Note: there should be a detailed process, no process do not send

360 °× 1 / 5 = 72 ° --- the degree of the central angle of Chinese books and foreign language books
360 °× 1 / 10 = 36 ° --- the degree of the center angle of a circle in mathematics books
360 °× 1 / 6 = 60 ° --- the degree of the central angle of the circle in the books of history, geography and Biology
360 ° - 72 ° - 36 ° - 60 ° = 192 ° -- the central angle of other books
