Yechim qadamlari

-9 olish uchun 80 dan 89 ni ayirish.

$$\frac{3\left(-9\right)+6}{76-2-57}+\frac{36}{45}$$

-27 hosil qilish uchun 3 va -9 ni ko'paytirish.

$$\frac{-27+6}{76-2-57}+\frac{36}{45}$$

-21 olish uchun -27 va 6'ni qo'shing.

$$\frac{-21}{76-2-57}+\frac{36}{45}$$

74 olish uchun 76 dan 2 ni ayirish.

$$\frac{-21}{74-57}+\frac{36}{45}$$

17 olish uchun 74 dan 57 ni ayirish.

$$\frac{-21}{17}+\frac{36}{45}$$

\frac{-21}{17} kasri manfiy belgini olib tashlash bilan -\frac{21}{17} sifatida qayta yozilishi mumkin.

$$-\frac{21}{17}+\frac{36}{45}$$

\frac{36}{45} ulushini 9 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{21}{17}+\frac{4}{5}$$

17 va 5 ning eng kichik umumiy karralisi 85 ga teng. -\frac{21}{17} va \frac{4}{5} ni 85 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{105}{85}+\frac{68}{85}$$

-\frac{105}{85} va \frac{68}{85} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-105+68}{85}$$

-37 olish uchun -105 va 68'ni qo'shing.

$$-\frac{37}{85}$$
