$$\frac{20}{9}\approx 2,222222222$$

Yechim qadamlari

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

$$\frac{-\frac{9+2}{3}}{-\frac{1\times 7+4}{7}}-\frac{1}{9}$$

11 olish uchun 9 va 2'ni qo'shing.

$$\frac{-\frac{11}{3}}{-\frac{1\times 7+4}{7}}-\frac{1}{9}$$

7 hosil qilish uchun 1 va 7 ni ko'paytirish.

$$\frac{-\frac{11}{3}}{-\frac{7+4}{7}}-\frac{1}{9}$$

11 olish uchun 7 va 4'ni qo'shing.

$$\frac{-\frac{11}{3}}{-\frac{11}{7}}-\frac{1}{9}$$

-\frac{11}{3} ni -\frac{11}{7} ga bo'lish -\frac{11}{3} ga k'paytirish -\frac{11}{7} ga qaytarish.

$$-\frac{11}{3}\left(-\frac{7}{11}\right)-\frac{1}{9}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{11}{3} ni -\frac{7}{11} ga ko‘paytiring.

$$\frac{-11\left(-7\right)}{3\times 11}-\frac{1}{9}$$

\frac{-11\left(-7\right)}{3\times 11} kasridagi ko‘paytirishlarni bajaring.

$$\frac{77}{33}-\frac{1}{9}$$

\frac{77}{33} ulushini 11 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{7}{3}-\frac{1}{9}$$

3 va 9 ning eng kichik umumiy karralisi 9 ga teng. \frac{7}{3} va \frac{1}{9} ni 9 maxraj bilan kasrlarga aylantirib oling.

$$\frac{21}{9}-\frac{1}{9}$$

\frac{21}{9} va \frac{1}{9} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{21-1}{9}$$

20 olish uchun 21 dan 1 ni ayirish.

$$\frac{20}{9}$$

Omil

$$\frac{2 ^ {2} \cdot 5}{3 ^ {2}} = 2\frac{2}{9} = 2,2222222222222223$$
