Yechim qadamlari

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

$$7+\frac{8\left(8+3\times 4\right)}{3+4\times 9}$$

12 hosil qilish uchun 3 va 4 ni ko'paytirish.

$$7+\frac{8\left(8+12\right)}{3+4\times 9}$$

20 olish uchun 8 va 12'ni qo'shing.

$$7+\frac{8\times 20}{3+4\times 9}$$

160 hosil qilish uchun 8 va 20 ni ko'paytirish.

$$7+\frac{160}{3+4\times 9}$$

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

$$7+\frac{160}{3+36}$$

39 olish uchun 3 va 36'ni qo'shing.

$$7+\frac{160}{39}$$

7 ni \frac{273}{39} kasrga o‘giring.

$$\frac{273}{39}+\frac{160}{39}$$

\frac{273}{39} va \frac{160}{39} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{273+160}{39}$$

433 olish uchun 273 va 160'ni qo'shing.

$$\frac{433}{39}$$

Omil

$$\frac{433}{3 \cdot 13} = 11\frac{4}{39} = 11,102564102564102$$
