Yechim qadamlari

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

$$\frac{18+1}{6}+2+\frac{2\times 3+1}{3}$$

19 olish uchun 18 va 1'ni qo'shing.

$$\frac{19}{6}+2+\frac{2\times 3+1}{3}$$

2 ni \frac{12}{6} kasrga o‘giring.

$$\frac{19}{6}+\frac{12}{6}+\frac{2\times 3+1}{3}$$

\frac{19}{6} va \frac{12}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{19+12}{6}+\frac{2\times 3+1}{3}$$

31 olish uchun 19 va 12'ni qo'shing.

$$\frac{31}{6}+\frac{2\times 3+1}{3}$$

6 hosil qilish uchun 2 va 3 ni ko'paytirish.

$$\frac{31}{6}+\frac{6+1}{3}$$

7 olish uchun 6 va 1'ni qo'shing.

$$\frac{31}{6}+\frac{7}{3}$$

6 va 3 ning eng kichik umumiy karralisi 6 ga teng. \frac{31}{6} va \frac{7}{3} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$\frac{31}{6}+\frac{14}{6}$$

\frac{31}{6} va \frac{14}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{31+14}{6}$$

45 olish uchun 31 va 14'ni qo'shing.

$$\frac{45}{6}$$

\frac{45}{6} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{15}{2}$$

Omil

$$\frac{3 \cdot 5}{2} = 7\frac{1}{2} = 7,5$$
