Yechim qadamlari

57 hosil qilish uchun 3 va 19 ni ko'paytirish.

$$\frac{57+1}{19}-\frac{2\times 29+6}{29}$$

58 olish uchun 57 va 1'ni qo'shing.

$$\frac{58}{19}-\frac{2\times 29+6}{29}$$

58 hosil qilish uchun 2 va 29 ni ko'paytirish.

$$\frac{58}{19}-\frac{58+6}{29}$$

64 olish uchun 58 va 6'ni qo'shing.

$$\frac{58}{19}-\frac{64}{29}$$

19 va 29 ning eng kichik umumiy karralisi 551 ga teng. \frac{58}{19} va \frac{64}{29} ni 551 maxraj bilan kasrlarga aylantirib oling.

$$\frac{1682}{551}-\frac{1216}{551}$$

\frac{1682}{551} va \frac{1216}{551} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{1682-1216}{551}$$

466 olish uchun 1682 dan 1216 ni ayirish.

$$\frac{466}{551}$$

Omil
