$$\left(8-\frac{3}{4}\times \frac{1}{6}\right)\times \frac{1}{3}-9$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{3}{4} ni \frac{1}{6} ga ko‘paytiring.

$$\left(8-\frac{3\times 1}{4\times 6}\right)\times \frac{1}{3}-9$$

\frac{3\times 1}{4\times 6} kasridagi ko‘paytirishlarni bajaring.

$$\left(8-\frac{3}{24}\right)\times \frac{1}{3}-9$$

\frac{3}{24} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\left(8-\frac{1}{8}\right)\times \frac{1}{3}-9$$

8 ni \frac{64}{8} kasrga o‘giring.

$$\left(\frac{64}{8}-\frac{1}{8}\right)\times \frac{1}{3}-9$$

63 olish uchun 64 dan 1 ni ayirish.

$$\frac{63}{8}\times \frac{1}{3}-9$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{63}{8} ni \frac{1}{3} ga ko‘paytiring.

$$\frac{63\times 1}{8\times 3}-9$$

\frac{63\times 1}{8\times 3} kasridagi ko‘paytirishlarni bajaring.

$$\frac{63}{24}-9$$

\frac{63}{24} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{21}{8}-9$$

9 ni \frac{72}{8} kasrga o‘giring.

$$\frac{21}{8}-\frac{72}{8}$$

\frac{21}{8} va \frac{72}{8} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{21-72}{8}$$

-51 olish uchun 21 dan 72 ni ayirish.
