Yechim qadamlari

8 hosil qilish uchun 1 va 8 ni ko'paytirish.

$$\frac{8+1}{8}+\frac{5\times 20+3}{20}+\frac{6\times 10+5}{10}$$

9 olish uchun 8 va 1'ni qo'shing.

$$\frac{9}{8}+\frac{5\times 20+3}{20}+\frac{6\times 10+5}{10}$$

100 hosil qilish uchun 5 va 20 ni ko'paytirish.

$$\frac{9}{8}+\frac{100+3}{20}+\frac{6\times 10+5}{10}$$

103 olish uchun 100 va 3'ni qo'shing.

$$\frac{9}{8}+\frac{103}{20}+\frac{6\times 10+5}{10}$$

8 va 20 ning eng kichik umumiy karralisi 40 ga teng. \frac{9}{8} va \frac{103}{20} ni 40 maxraj bilan kasrlarga aylantirib oling.

$$\frac{45}{40}+\frac{206}{40}+\frac{6\times 10+5}{10}$$

\frac{45}{40} va \frac{206}{40} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{45+206}{40}+\frac{6\times 10+5}{10}$$

251 olish uchun 45 va 206'ni qo'shing.

$$\frac{251}{40}+\frac{6\times 10+5}{10}$$

60 hosil qilish uchun 6 va 10 ni ko'paytirish.

$$\frac{251}{40}+\frac{60+5}{10}$$

65 olish uchun 60 va 5'ni qo'shing.

$$\frac{251}{40}+\frac{65}{10}$$

\frac{65}{10} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{251}{40}+\frac{13}{2}$$

40 va 2 ning eng kichik umumiy karralisi 40 ga teng. \frac{251}{40} va \frac{13}{2} ni 40 maxraj bilan kasrlarga aylantirib oling.

$$\frac{251}{40}+\frac{260}{40}$$

\frac{251}{40} va \frac{260}{40} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{251+260}{40}$$

511 olish uchun 251 va 260'ni qo'shing.

$$\frac{511}{40}$$
