Yechim qadamlari

\frac{1}{3} ni \frac{2}{3} ga bo'lish \frac{1}{3} ga k'paytirish \frac{2}{3} ga qaytarish.

$$\frac{1}{3}\times \frac{3}{2}+\frac{2}{1,5}+\frac{3}{5}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{1}{3} ni \frac{3}{2} ga ko‘paytiring.

$$\frac{1\times 3}{3\times 2}+\frac{2}{1,5}+\frac{3}{5}$$

Surat va maxrajdagi ikkala 3 ni qisqartiring.

$$\frac{1}{2}+\frac{2}{1,5}+\frac{3}{5}$$

\frac{2}{1,5} kasrini uning surat va maxrajini 10 ga ko‘paytirish bilan kengaytiring.

$$\frac{1}{2}+\frac{20}{15}+\frac{3}{5}$$

\frac{20}{15} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{1}{2}+\frac{4}{3}+\frac{3}{5}$$

2 va 3 ning eng kichik umumiy karralisi 6 ga teng. \frac{1}{2} va \frac{4}{3} ni 6 maxraj bilan kasrlarga aylantirib oling.

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

\frac{3}{6} va \frac{8}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

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

11 olish uchun 3 va 8'ni qo'shing.

$$\frac{11}{6}+\frac{3}{5}$$

6 va 5 ning eng kichik umumiy karralisi 30 ga teng. \frac{11}{6} va \frac{3}{5} ni 30 maxraj bilan kasrlarga aylantirib oling.

$$\frac{55}{30}+\frac{18}{30}$$

\frac{55}{30} va \frac{18}{30} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{55+18}{30}$$

73 olish uchun 55 va 18'ni qo'shing.

$$\frac{73}{30}$$

Omil

$$\frac{73}{2 \cdot 3 \cdot 5} = 2\frac{13}{30} = 2,433333333333333$$
