Yechim qadamlari

-\frac{1}{3}\times 1000 ni yagona kasrga aylantiring.

$$\frac{-1000}{3}+\frac{13}{2}\times 100-300$$

\frac{-1000}{3} kasri manfiy belgini olib tashlash bilan -\frac{1000}{3} sifatida qayta yozilishi mumkin.

$$-\frac{1000}{3}+\frac{13}{2}\times 100-300$$

\frac{13}{2}\times 100 ni yagona kasrga aylantiring.

$$-\frac{1000}{3}+\frac{13\times 100}{2}-300$$

1300 hosil qilish uchun 13 va 100 ni ko'paytirish.

$$-\frac{1000}{3}+\frac{1300}{2}-300$$

650 ni olish uchun 1300 ni 2 ga bo‘ling.

$$-\frac{1000}{3}+650-300$$

650 ni \frac{1950}{3} kasrga o‘giring.

$$-\frac{1000}{3}+\frac{1950}{3}-300$$

-\frac{1000}{3} va \frac{1950}{3} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-1000+1950}{3}-300$$

950 olish uchun -1000 va 1950'ni qo'shing.

$$\frac{950}{3}-300$$

300 ni \frac{900}{3} kasrga o‘giring.

$$\frac{950}{3}-\frac{900}{3}$$

\frac{950}{3} va \frac{900}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{950-900}{3}$$

50 olish uchun 950 dan 900 ni ayirish.

$$\frac{50}{3}$$

Omil

$$\frac{2 \cdot 5 ^ {2}}{3} = 16\frac{2}{3} = 16,666666666666668$$
