Yechim qadamlari

-192 hosil qilish uchun 3 va -64 ni ko'paytirish.

$$\frac{-192}{-\frac{7}{31}}-64\times \frac{3\times 7+3}{7}$$

-192 ni -\frac{7}{31} ga bo'lish -192 ga k'paytirish -\frac{7}{31} ga qaytarish.

$$-192\left(-\frac{31}{7}\right)-64\times \frac{3\times 7+3}{7}$$

-192\left(-\frac{31}{7}\right) ni yagona kasrga aylantiring.

$$\frac{-192\left(-31\right)}{7}-64\times \frac{3\times 7+3}{7}$$

5952 hosil qilish uchun -192 va -31 ni ko'paytirish.

$$\frac{5952}{7}-64\times \frac{3\times 7+3}{7}$$

21 hosil qilish uchun 3 va 7 ni ko'paytirish.

$$\frac{5952}{7}-64\times \frac{21+3}{7}$$

24 olish uchun 21 va 3'ni qo'shing.

$$\frac{5952}{7}-64\times \frac{24}{7}$$

-64\times \frac{24}{7} ni yagona kasrga aylantiring.

$$\frac{5952}{7}+\frac{-64\times 24}{7}$$

-1536 hosil qilish uchun -64 va 24 ni ko'paytirish.

$$\frac{5952}{7}+\frac{-1536}{7}$$

\frac{-1536}{7} kasri manfiy belgini olib tashlash bilan -\frac{1536}{7} sifatida qayta yozilishi mumkin.

$$\frac{5952}{7}-\frac{1536}{7}$$

\frac{5952}{7} va \frac{1536}{7} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{5952-1536}{7}$$

4416 olish uchun 5952 dan 1536 ni ayirish.

$$\frac{4416}{7}$$

Omil

$$\frac{2 ^ {6} \cdot 3 \cdot 23}{7} = 630\frac{6}{7} = 630,8571428571429$$
