Yechim qadamlari

2 ni \frac{8}{4} kasrga o‘giring.

$$\frac{\frac{9}{4}+\frac{8}{4}}{\frac{4}{3}-4}$$

\frac{9}{4} va \frac{8}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{\frac{9+8}{4}}{\frac{4}{3}-4}$$

17 olish uchun 9 va 8'ni qo'shing.

$$\frac{\frac{17}{4}}{\frac{4}{3}-4}$$

4 ni \frac{12}{3} kasrga o‘giring.

$$\frac{\frac{17}{4}}{\frac{4}{3}-\frac{12}{3}}$$

\frac{4}{3} va \frac{12}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{\frac{17}{4}}{\frac{4-12}{3}}$$

-8 olish uchun 4 dan 12 ni ayirish.

$$\frac{\frac{17}{4}}{-\frac{8}{3}}$$

\frac{17}{4} ni -\frac{8}{3} ga bo'lish \frac{17}{4} ga k'paytirish -\frac{8}{3} ga qaytarish.

$$\frac{17}{4}\left(-\frac{3}{8}\right)$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{17}{4} ni -\frac{3}{8} ga ko‘paytiring.

$$\frac{17\left(-3\right)}{4\times 8}$$

\frac{17\left(-3\right)}{4\times 8} kasridagi ko‘paytirishlarni bajaring.

$$\frac{-51}{32}$$

\frac{-51}{32} kasri manfiy belgini olib tashlash bilan -\frac{51}{32} sifatida qayta yozilishi mumkin.

$$-\frac{51}{32}$$

Omil

$$-\frac{51}{32} = -1\frac{19}{32} = -1,59375$$
