$$\frac{ 3 }{ 4 } + \frac{ 5 }{ 8 } + \frac{ 6 }{ 9 }$$

Baholash

$$\frac{49}{24}\approx 2,041666667$$

Yechim qadamlari

4 va 8 ning eng kichik umumiy karralisi 8 ga teng. \frac{3}{4} va \frac{5}{8} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\frac{6}{8}+\frac{5}{8}+\frac{6}{9}$$

\frac{6}{8} va \frac{5}{8} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{6+5}{8}+\frac{6}{9}$$

11 olish uchun 6 va 5'ni qo'shing.

$$\frac{11}{8}+\frac{6}{9}$$

\frac{6}{9} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{11}{8}+\frac{2}{3}$$

8 va 3 ning eng kichik umumiy karralisi 24 ga teng. \frac{11}{8} va \frac{2}{3} ni 24 maxraj bilan kasrlarga aylantirib oling.

$$\frac{33}{24}+\frac{16}{24}$$

\frac{33}{24} va \frac{16}{24} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{33+16}{24}$$

49 olish uchun 33 va 16'ni qo'shing.

$$\frac{49}{24}$$

Omil

$$\frac{7 ^ {2}}{2 ^ {3} \cdot 3} = 2\frac{1}{24} = 2,0416666666666665$$
