Yechim qadamlari

60 hosil qilish uchun 5 va 12 ni ko'paytirish.

$$\frac{60+1}{12}-\frac{3\times 18+13}{18}$$

61 olish uchun 60 va 1'ni qo'shing.

$$\frac{61}{12}-\frac{3\times 18+13}{18}$$

54 hosil qilish uchun 3 va 18 ni ko'paytirish.

$$\frac{61}{12}-\frac{54+13}{18}$$

67 olish uchun 54 va 13'ni qo'shing.

$$\frac{61}{12}-\frac{67}{18}$$

12 va 18 ning eng kichik umumiy karralisi 36 ga teng. \frac{61}{12} va \frac{67}{18} ni 36 maxraj bilan kasrlarga aylantirib oling.

$$\frac{183}{36}-\frac{134}{36}$$

\frac{183}{36} va \frac{134}{36} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{183-134}{36}$$

49 olish uchun 183 dan 134 ni ayirish.

$$\frac{49}{36}$$

Omil

$$\frac{7 ^ {2}}{2 ^ {2} \cdot 3 ^ {2}} = 1\frac{13}{36} = 1,3611111111111112$$
