Yechim qadamlari

44 hosil qilish uchun 4 va 11 ni ko'paytirish.

$$\frac{\frac{7}{11}}{\frac{44+7}{11}-\frac{13\times 13+4}{13}+\frac{9\times 13+4}{13}}$$

51 olish uchun 44 va 7'ni qo'shing.

$$\frac{\frac{7}{11}}{\frac{51}{11}-\frac{13\times 13+4}{13}+\frac{9\times 13+4}{13}}$$

169 hosil qilish uchun 13 va 13 ni ko'paytirish.

$$\frac{\frac{7}{11}}{\frac{51}{11}-\frac{169+4}{13}+\frac{9\times 13+4}{13}}$$

173 olish uchun 169 va 4'ni qo'shing.

$$\frac{\frac{7}{11}}{\frac{51}{11}-\frac{173}{13}+\frac{9\times 13+4}{13}}$$

11 va 13 ning eng kichik umumiy karralisi 143 ga teng. \frac{51}{11} va \frac{173}{13} ni 143 maxraj bilan kasrlarga aylantirib oling.

$$\frac{\frac{7}{11}}{\frac{663}{143}-\frac{1903}{143}+\frac{9\times 13+4}{13}}$$

\frac{663}{143} va \frac{1903}{143} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{\frac{7}{11}}{\frac{663-1903}{143}+\frac{9\times 13+4}{13}}$$

-1240 olish uchun 663 dan 1903 ni ayirish.

$$\frac{\frac{7}{11}}{-\frac{1240}{143}+\frac{9\times 13+4}{13}}$$

117 hosil qilish uchun 9 va 13 ni ko'paytirish.

$$\frac{\frac{7}{11}}{-\frac{1240}{143}+\frac{117+4}{13}}$$

121 olish uchun 117 va 4'ni qo'shing.

$$\frac{\frac{7}{11}}{-\frac{1240}{143}+\frac{121}{13}}$$

143 va 13 ning eng kichik umumiy karralisi 143 ga teng. -\frac{1240}{143} va \frac{121}{13} ni 143 maxraj bilan kasrlarga aylantirib oling.

$$\frac{\frac{7}{11}}{-\frac{1240}{143}+\frac{1331}{143}}$$

-\frac{1240}{143} va \frac{1331}{143} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{\frac{7}{11}}{\frac{-1240+1331}{143}}$$

91 olish uchun -1240 va 1331'ni qo'shing.

$$\frac{\frac{7}{11}}{\frac{91}{143}}$$

\frac{91}{143} ulushini 13 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{\frac{7}{11}}{\frac{7}{11}}$$

1 ni olish uchun \frac{7}{11} ni \frac{7}{11} ga bo‘ling.
