Yechim qadamlari

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

$$1+\frac{12}{3+4\times 9}$$

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

$$1+\frac{12}{3+36}$$

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

$$1+\frac{12}{39}$$

\frac{12}{39} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$1+\frac{4}{13}$$

1 ni \frac{13}{13} kasrga o‘giring.

$$\frac{13}{13}+\frac{4}{13}$$

\frac{13}{13} va \frac{4}{13} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{13+4}{13}$$

17 olish uchun 13 va 4'ni qo'shing.

$$\frac{17}{13}$$

Omil

$$\frac{17}{13} = 1\frac{4}{13} = 1,3076923076923077$$
