Yechim qadamlari

1 ni olish uchun 3 ni 3 ga bo‘ling.

$$\left(\frac{1}{2}+\frac{2}{3}-1\right)\left(2+\frac{1}{3}-\frac{2\times 9+1}{9}\right)$$

2 va 3 ning eng kichik umumiy karralisi 6 ga teng. \frac{1}{2} va \frac{2}{3} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$\left(\frac{3}{6}+\frac{4}{6}-1\right)\left(2+\frac{1}{3}-\frac{2\times 9+1}{9}\right)$$

\frac{3}{6} va \frac{4}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\left(\frac{3+4}{6}-1\right)\left(2+\frac{1}{3}-\frac{2\times 9+1}{9}\right)$$

7 olish uchun 3 va 4'ni qo'shing.

$$\left(\frac{7}{6}-1\right)\left(2+\frac{1}{3}-\frac{2\times 9+1}{9}\right)$$

1 ni \frac{6}{6} kasrga o‘giring.

$$\left(\frac{7}{6}-\frac{6}{6}\right)\left(2+\frac{1}{3}-\frac{2\times 9+1}{9}\right)$$

\frac{7}{6} va \frac{6}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{7-6}{6}\left(2+\frac{1}{3}-\frac{2\times 9+1}{9}\right)$$

1 olish uchun 7 dan 6 ni ayirish.

$$\frac{1}{6}\left(2+\frac{1}{3}-\frac{2\times 9+1}{9}\right)$$

2 ni \frac{6}{3} kasrga o‘giring.

$$\frac{1}{6}\left(\frac{6}{3}+\frac{1}{3}-\frac{2\times 9+1}{9}\right)$$

\frac{6}{3} va \frac{1}{3} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{1}{6}\left(\frac{6+1}{3}-\frac{2\times 9+1}{9}\right)$$

7 olish uchun 6 va 1'ni qo'shing.

$$\frac{1}{6}\left(\frac{7}{3}-\frac{2\times 9+1}{9}\right)$$

18 hosil qilish uchun 2 va 9 ni ko'paytirish.

$$\frac{1}{6}\left(\frac{7}{3}-\frac{18+1}{9}\right)$$

19 olish uchun 18 va 1'ni qo'shing.

$$\frac{1}{6}\left(\frac{7}{3}-\frac{19}{9}\right)$$

3 va 9 ning eng kichik umumiy karralisi 9 ga teng. \frac{7}{3} va \frac{19}{9} ni 9 maxraj bilan kasrlarga aylantirib oling.

$$\frac{1}{6}\left(\frac{21}{9}-\frac{19}{9}\right)$$

\frac{21}{9} va \frac{19}{9} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{1}{6}\times \frac{21-19}{9}$$

2 olish uchun 21 dan 19 ni ayirish.

$$\frac{1}{6}\times \frac{2}{9}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{1}{6} ni \frac{2}{9} ga ko‘paytiring.

$$\frac{1\times 2}{6\times 9}$$

\frac{1\times 2}{6\times 9} kasridagi ko‘paytirishlarni bajaring.

$$\frac{2}{54}$$

\frac{2}{54} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{1}{27}$$
