Yechim qadamlari

8 va 15 ning eng kichik umumiy karralisi 120 ga teng. \frac{5}{8} va \frac{7}{15} ni 120 maxraj bilan kasrlarga aylantirib oling.

$$\frac{75}{120}-\frac{56}{120}+\frac{3}{32}+\frac{11}{75}$$

\frac{75}{120} va \frac{56}{120} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{75-56}{120}+\frac{3}{32}+\frac{11}{75}$$

19 olish uchun 75 dan 56 ni ayirish.

$$\frac{19}{120}+\frac{3}{32}+\frac{11}{75}$$

120 va 32 ning eng kichik umumiy karralisi 480 ga teng. \frac{19}{120} va \frac{3}{32} ni 480 maxraj bilan kasrlarga aylantirib oling.

$$\frac{76}{480}+\frac{45}{480}+\frac{11}{75}$$

\frac{76}{480} va \frac{45}{480} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{76+45}{480}+\frac{11}{75}$$

121 olish uchun 76 va 45'ni qo'shing.

$$\frac{121}{480}+\frac{11}{75}$$

480 va 75 ning eng kichik umumiy karralisi 2400 ga teng. \frac{121}{480} va \frac{11}{75} ni 2400 maxraj bilan kasrlarga aylantirib oling.

$$\frac{605}{2400}+\frac{352}{2400}$$

\frac{605}{2400} va \frac{352}{2400} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{605+352}{2400}$$

957 olish uchun 605 va 352'ni qo'shing.

$$\frac{957}{2400}$$

\frac{957}{2400} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{319}{800}$$

Omil

$$\frac{11 \cdot 29}{2 ^ {5} \cdot 5 ^ {2}} = 0,39875$$
