Yechim qadamlari

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

$$\frac{7}{12}+\frac{1}{2}+\frac{1}{2}$$

12 va 2 ning eng kichik umumiy karralisi 12 ga teng. \frac{7}{12} va \frac{1}{2} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{7}{12}+\frac{6}{12}+\frac{1}{2}$$

\frac{7}{12} va \frac{6}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{7+6}{12}+\frac{1}{2}$$

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

$$\frac{13}{12}+\frac{1}{2}$$

12 va 2 ning eng kichik umumiy karralisi 12 ga teng. \frac{13}{12} va \frac{1}{2} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{13}{12}+\frac{6}{12}$$

\frac{13}{12} va \frac{6}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{13+6}{12}$$

19 olish uchun 13 va 6'ni qo'shing.

$$\frac{19}{12}$$

Omil

$$\frac{19}{2 ^ {2} \cdot 3} = 1\frac{7}{12} = 1,5833333333333333$$
