\frac{4}{7}-\left(-\frac{5}{3}\right)
\frac{-5}{3} kasri manfiy belgini olib tashlash bilan -\frac{5}{3} sifatida qayta yozilishi mumkin.
\frac{4}{7}+\frac{5}{3}
-\frac{5}{3} ning teskarisi \frac{5}{3} ga teng.
\frac{12}{21}+\frac{35}{21}
7 va 3 ning eng kichik umumiy karralisi 21 ga teng. \frac{4}{7} va \frac{5}{3} ni 21 maxraj bilan kasrlarga aylantirib oling.
\frac{12+35}{21}
\frac{12}{21} va \frac{35}{21} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.
\frac{47}{21}
47 olish uchun 12 va 35'ni qo'shing.
