Natural va butun sonlar

5 - §. Kasrlar.
Siz kasrlar va undagi bo’ladiga deyarli barcha amallar haqida tushunchaga egasiz. Lekin har qanday kasrlarni zanjirli kasrga aylantirish tushunchasiga batafsil ma’lumotlarga ega emassiz. Misol yordamida quyidagi noto’g’ri kasrni zanjirli kasrga aylantirishni ko’rib chiqamiz.



ko’rinishdagi belgilash kasrning zanjirli kasrga o’tishdagi belgilashdir.
