Yechim qadamlari

\frac{-11}{12} kasri manfiy belgini olib tashlash bilan -\frac{11}{12} sifatida qayta yozilishi mumkin.

$$-\frac{11}{12}+\frac{-13}{15}+\frac{14}{17}$$

\frac{-13}{15} kasri manfiy belgini olib tashlash bilan -\frac{13}{15} sifatida qayta yozilishi mumkin.

$$-\frac{11}{12}-\frac{13}{15}+\frac{14}{17}$$

12 va 15 ning eng kichik umumiy karralisi 60 ga teng. -\frac{11}{12} va \frac{13}{15} ni 60 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{55}{60}-\frac{52}{60}+\frac{14}{17}$$

-\frac{55}{60} va \frac{52}{60} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-55-52}{60}+\frac{14}{17}$$

-107 olish uchun -55 dan 52 ni ayirish.

$$-\frac{107}{60}+\frac{14}{17}$$

60 va 17 ning eng kichik umumiy karralisi 1020 ga teng. -\frac{107}{60} va \frac{14}{17} ni 1020 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{1819}{1020}+\frac{840}{1020}$$

-\frac{1819}{1020} va \frac{840}{1020} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-1819+840}{1020}$$

-979 olish uchun -1819 va 840'ni qo'shing.

$$-\frac{979}{1020}$$
