Yechim qadamlari

6\times \frac{3}{5} ni yagona kasrga aylantiring.

$$\frac{10-\frac{6\times 3}{5}}{15\times \frac{4}{5}}+\frac{12}{5}$$

18 hosil qilish uchun 6 va 3 ni ko'paytirish.

$$\frac{10-\frac{18}{5}}{15\times \frac{4}{5}}+\frac{12}{5}$$

10 ni \frac{50}{5} kasrga o‘giring.

$$\frac{\frac{50}{5}-\frac{18}{5}}{15\times \frac{4}{5}}+\frac{12}{5}$$

\frac{50}{5} va \frac{18}{5} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{\frac{50-18}{5}}{15\times \frac{4}{5}}+\frac{12}{5}$$

32 olish uchun 50 dan 18 ni ayirish.

$$\frac{\frac{32}{5}}{15\times \frac{4}{5}}+\frac{12}{5}$$

15\times \frac{4}{5} ni yagona kasrga aylantiring.

$$\frac{\frac{32}{5}}{\frac{15\times 4}{5}}+\frac{12}{5}$$

60 hosil qilish uchun 15 va 4 ni ko'paytirish.

$$\frac{\frac{32}{5}}{\frac{60}{5}}+\frac{12}{5}$$

12 ni olish uchun 60 ni 5 ga bo‘ling.

$$\frac{\frac{32}{5}}{12}+\frac{12}{5}$$

\frac{\frac{32}{5}}{12} ni yagona kasrga aylantiring.

$$\frac{32}{5\times 12}+\frac{12}{5}$$

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

$$\frac{32}{60}+\frac{12}{5}$$

\frac{32}{60} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{8}{15}+\frac{12}{5}$$

15 va 5 ning eng kichik umumiy karralisi 15 ga teng. \frac{8}{15} va \frac{12}{5} ni 15 maxraj bilan kasrlarga aylantirib oling.

$$\frac{8}{15}+\frac{36}{15}$$

\frac{8}{15} va \frac{36}{15} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{8+36}{15}$$

44 olish uchun 8 va 36'ni qo'shing.

$$\frac{44}{15}$$

Omil

$$\frac{2 ^ {2} \cdot 11}{3 \cdot 5} = 2\frac{14}{15} = 2,933333333333333$$
