Yechim qadamlari

11 olish uchun 8 va 3'ni qo'shing.

$$11+5\times 4-\frac{15}{11}-6-9\times 4$$

20 hosil qilish uchun 5 va 4 ni ko'paytirish.

$$11+20-\frac{15}{11}-6-9\times 4$$

31 olish uchun 11 va 20'ni qo'shing.

$$31-\frac{15}{11}-6-9\times 4$$

31 ni \frac{341}{11} kasrga o‘giring.

$$\frac{341}{11}-\frac{15}{11}-6-9\times 4$$

\frac{341}{11} va \frac{15}{11} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{341-15}{11}-6-9\times 4$$

326 olish uchun 341 dan 15 ni ayirish.

$$\frac{326}{11}-6-9\times 4$$

6 ni \frac{66}{11} kasrga o‘giring.

$$\frac{326}{11}-\frac{66}{11}-9\times 4$$

\frac{326}{11} va \frac{66}{11} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{326-66}{11}-9\times 4$$

260 olish uchun 326 dan 66 ni ayirish.

$$\frac{260}{11}-9\times 4$$

36 hosil qilish uchun 9 va 4 ni ko'paytirish.

$$\frac{260}{11}-36$$

36 ni \frac{396}{11} kasrga o‘giring.

$$\frac{260}{11}-\frac{396}{11}$$

\frac{260}{11} va \frac{396}{11} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{260-396}{11}$$

-136 olish uchun 260 dan 396 ni ayirish.

$$-\frac{136}{11}$$

Omil

$$-\frac{136}{11} = -12\frac{4}{11} = -12,363636363636363$$
