Yechim qadamlari

6 va 4 ning eng kichik umumiy karralisi 12 ga teng. \frac{5}{6} va \frac{3}{4} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{10}{12}+\frac{9}{12}+\frac{2}{3}$$

\frac{10}{12} va \frac{9}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{10+9}{12}+\frac{2}{3}$$

19 olish uchun 10 va 9'ni qo'shing.

$$\frac{19}{12}+\frac{2}{3}$$

12 va 3 ning eng kichik umumiy karralisi 12 ga teng. \frac{19}{12} va \frac{2}{3} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{19}{12}+\frac{8}{12}$$

\frac{19}{12} va \frac{8}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{19+8}{12}$$

27 olish uchun 19 va 8'ni qo'shing.

$$\frac{27}{12}$$

\frac{27}{12} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{9}{4}$$
