Yechim qadamlari

\frac{-1}{10} kasri manfiy belgini olib tashlash bilan -\frac{1}{10} sifatida qayta yozilishi mumkin.

$$-\frac{1}{10}-\left(-\frac{6\times 2+1}{2}\right)$$

12 hosil qilish uchun 6 va 2 ni ko'paytirish.

$$-\frac{1}{10}-\left(-\frac{12+1}{2}\right)$$

13 olish uchun 12 va 1'ni qo'shing.

$$-\frac{1}{10}-\left(-\frac{13}{2}\right)$$

-\frac{13}{2} ning teskarisi \frac{13}{2} ga teng.

$$-\frac{1}{10}+\frac{13}{2}$$

10 va 2 ning eng kichik umumiy karralisi 10 ga teng. -\frac{1}{10} va \frac{13}{2} ni 10 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{1}{10}+\frac{65}{10}$$

-\frac{1}{10} va \frac{65}{10} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-1+65}{10}$$

64 olish uchun -1 va 65'ni qo'shing.

$$\frac{64}{10}$$

\frac{64}{10} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{32}{5}$$

Omil

$$\frac{2 ^ {5}}{5} = 6\frac{2}{5} = 6,4$$
