Yechim qadamlari

\frac{35}{15} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{7}{3}+3-\frac{5}{4}+\frac{2}{5}\times \frac{15}{2}-12\times 5$$

3 ni \frac{9}{3} kasrga o‘giring.

$$\frac{7}{3}+\frac{9}{3}-\frac{5}{4}+\frac{2}{5}\times \frac{15}{2}-12\times 5$$

\frac{7}{3} va \frac{9}{3} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{7+9}{3}-\frac{5}{4}+\frac{2}{5}\times \frac{15}{2}-12\times 5$$

16 olish uchun 7 va 9'ni qo'shing.

$$\frac{16}{3}-\frac{5}{4}+\frac{2}{5}\times \frac{15}{2}-12\times 5$$

3 va 4 ning eng kichik umumiy karralisi 12 ga teng. \frac{16}{3} va \frac{5}{4} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{64}{12}-\frac{15}{12}+\frac{2}{5}\times \frac{15}{2}-12\times 5$$

\frac{64}{12} va \frac{15}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{64-15}{12}+\frac{2}{5}\times \frac{15}{2}-12\times 5$$

49 olish uchun 64 dan 15 ni ayirish.

$$\frac{49}{12}+\frac{2}{5}\times \frac{15}{2}-12\times 5$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{2}{5} ni \frac{15}{2} ga ko‘paytiring.

$$\frac{49}{12}+\frac{2\times 15}{5\times 2}-12\times 5$$

Surat va maxrajdagi ikkala 2 ni qisqartiring.

$$\frac{49}{12}+\frac{15}{5}-12\times 5$$

3 ni olish uchun 15 ni 5 ga bo‘ling.

$$\frac{49}{12}+3-12\times 5$$

3 ni \frac{36}{12} kasrga o‘giring.

$$\frac{49}{12}+\frac{36}{12}-12\times 5$$

\frac{49}{12} va \frac{36}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{49+36}{12}-12\times 5$$

85 olish uchun 49 va 36'ni qo'shing.

$$\frac{85}{12}-12\times 5$$

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

$$\frac{85}{12}-60$$

60 ni \frac{720}{12} kasrga o‘giring.

$$\frac{85}{12}-\frac{720}{12}$$

\frac{85}{12} va \frac{720}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{85-720}{12}$$

-635 olish uchun 85 dan 720 ni ayirish.

$$-\frac{635}{12}$$

Omil

$$-\frac{635}{12} = -52\frac{11}{12} = -52,916666666666664$$
