$$\frac{47}{8}-\frac{23}{9}+1125-\frac{3\times 9+4}{9}$$

8 va 9 ning eng kichik umumiy karralisi 72 ga teng. \frac{47}{8} va \frac{23}{9} ni 72 maxraj bilan kasrlarga aylantirib oling.

$$\frac{423}{72}-\frac{184}{72}+1125-\frac{3\times 9+4}{9}$$

\frac{423}{72} va \frac{184}{72} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{423-184}{72}+1125-\frac{3\times 9+4}{9}$$

239 olish uchun 423 dan 184 ni ayirish.

$$\frac{239}{72}+1125-\frac{3\times 9+4}{9}$$

1125 ni \frac{81000}{72} kasrga o‘giring.

$$\frac{239}{72}+\frac{81000}{72}-\frac{3\times 9+4}{9}$$

\frac{239}{72} va \frac{81000}{72} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{239+81000}{72}-\frac{3\times 9+4}{9}$$

81239 olish uchun 239 va 81000'ni qo'shing.

$$\frac{81239}{72}-\frac{3\times 9+4}{9}$$

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

$$\frac{81239}{72}-\frac{27+4}{9}$$

31 olish uchun 27 va 4'ni qo'shing.

$$\frac{81239}{72}-\frac{31}{9}$$

72 va 9 ning eng kichik umumiy karralisi 72 ga teng. \frac{81239}{72} va \frac{31}{9} ni 72 maxraj bilan kasrlarga aylantirib oling.

$$\frac{81239}{72}-\frac{248}{72}$$

\frac{81239}{72} va \frac{248}{72} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{81239-248}{72}$$

80991 olish uchun 81239 dan 248 ni ayirish.

$$\frac{80991}{72}$$

\frac{80991}{72} ulushini 9 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{8999}{8}$$

Omil

$$\frac{8999}{2 ^ {3}} = 1124\frac{7}{8} = 1124,875$$
