Yechim qadamlari

7 va 5 ning eng kichik umumiy karralisi 35 ga teng. \frac{11}{7} va \frac{12}{5} ni 35 maxraj bilan kasrlarga aylantirib oling.

$$\frac{55}{35}+\frac{84}{35}-\frac{11}{7}$$

\frac{55}{35} va \frac{84}{35} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{55+84}{35}-\frac{11}{7}$$

139 olish uchun 55 va 84'ni qo'shing.

$$\frac{139}{35}-\frac{11}{7}$$

35 va 7 ning eng kichik umumiy karralisi 35 ga teng. \frac{139}{35} va \frac{11}{7} ni 35 maxraj bilan kasrlarga aylantirib oling.

$$\frac{139}{35}-\frac{55}{35}$$

\frac{139}{35} va \frac{55}{35} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{139-55}{35}$$

84 olish uchun 139 dan 55 ni ayirish.

$$\frac{84}{35}$$

\frac{84}{35} ulushini 7 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{12}{5}$$

Omil

$$\frac{2 ^ {2} \cdot 3}{5} = 2\frac{2}{5} = 2,4$$
