$$\frac{143}{40}=3,575$$

Yechim qadamlari

72 hosil qilish uchun 9 va 8 ni ko'paytirish.

$$\frac{72+3}{8}-\frac{5\times 5+4}{5}$$

75 olish uchun 72 va 3'ni qo'shing.

$$\frac{75}{8}-\frac{5\times 5+4}{5}$$

25 hosil qilish uchun 5 va 5 ni ko'paytirish.

$$\frac{75}{8}-\frac{25+4}{5}$$

29 olish uchun 25 va 4'ni qo'shing.

$$\frac{75}{8}-\frac{29}{5}$$

8 va 5 ning eng kichik umumiy karralisi 40 ga teng. \frac{75}{8} va \frac{29}{5} ni 40 maxraj bilan kasrlarga aylantirib oling.

$$\frac{375}{40}-\frac{232}{40}$$

\frac{375}{40} va \frac{232}{40} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{375-232}{40}$$

143 olish uchun 375 dan 232 ni ayirish.

$$\frac{143}{40}$$

Omil

$$\frac{11 \cdot 13}{2 ^ {3} \cdot 5} = 3\frac{23}{40} = 3,575$$
