Yechim qadamlari

7,2 olish uchun 1,2 va 6'ni qo'shing.

$$7,2-\left(\frac{\frac{3}{4}}{0,5}+\frac{1\times 3+1}{3}\right)$$

\frac{\frac{3}{4}}{0,5} ni yagona kasrga aylantiring.

$$7,2-\left(\frac{3}{4\times 0,5}+\frac{1\times 3+1}{3}\right)$$

2 hosil qilish uchun 4 va 0,5 ni ko'paytirish.

$$7,2-\left(\frac{3}{2}+\frac{1\times 3+1}{3}\right)$$

3 hosil qilish uchun 1 va 3 ni ko'paytirish.

$$7,2-\left(\frac{3}{2}+\frac{3+1}{3}\right)$$

4 olish uchun 3 va 1'ni qo'shing.

$$7,2-\left(\frac{3}{2}+\frac{4}{3}\right)$$

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

$$7,2-\left(\frac{9}{6}+\frac{8}{6}\right)$$

\frac{9}{6} va \frac{8}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$7,2-\frac{9+8}{6}$$

17 olish uchun 9 va 8'ni qo'shing.

$$7,2-\frac{17}{6}$$

7,2 o‘nlik raqamni uning \frac{72}{10} kasrga o‘giring. \frac{72}{10} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{36}{5}-\frac{17}{6}$$

5 va 6 ning eng kichik umumiy karralisi 30 ga teng. \frac{36}{5} va \frac{17}{6} ni 30 maxraj bilan kasrlarga aylantirib oling.

$$\frac{216}{30}-\frac{85}{30}$$

\frac{216}{30} va \frac{85}{30} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{216-85}{30}$$

131 olish uchun 216 dan 85 ni ayirish.

$$\frac{131}{30}$$

Omil

$$\frac{131}{2 \cdot 3 \cdot 5} = 4\frac{11}{30} = 4,366666666666666$$
