Yechim qadamlari

\frac{4}{10} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$6+\frac{2}{5}+\frac{8}{100}+\frac{2}{1000}$$

6 ni \frac{30}{5} kasrga o‘giring.

$$\frac{30}{5}+\frac{2}{5}+\frac{8}{100}+\frac{2}{1000}$$

\frac{30}{5} va \frac{2}{5} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{30+2}{5}+\frac{8}{100}+\frac{2}{1000}$$

32 olish uchun 30 va 2'ni qo'shing.

$$\frac{32}{5}+\frac{8}{100}+\frac{2}{1000}$$

\frac{8}{100} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{32}{5}+\frac{2}{25}+\frac{2}{1000}$$

5 va 25 ning eng kichik umumiy karralisi 25 ga teng. \frac{32}{5} va \frac{2}{25} ni 25 maxraj bilan kasrlarga aylantirib oling.

$$\frac{160}{25}+\frac{2}{25}+\frac{2}{1000}$$

\frac{160}{25} va \frac{2}{25} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{160+2}{25}+\frac{2}{1000}$$

162 olish uchun 160 va 2'ni qo'shing.

$$\frac{162}{25}+\frac{2}{1000}$$

\frac{2}{1000} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{162}{25}+\frac{1}{500}$$

25 va 500 ning eng kichik umumiy karralisi 500 ga teng. \frac{162}{25} va \frac{1}{500} ni 500 maxraj bilan kasrlarga aylantirib oling.

$$\frac{3240}{500}+\frac{1}{500}$$

\frac{3240}{500} va \frac{1}{500} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{3240+1}{500}$$

3241 olish uchun 3240 va 1'ni qo'shing.

$$\frac{3241}{500}$$

Omil

$$\frac{7 \cdot 463}{2 ^ {2} \cdot 5 ^ {3}} = 6\frac{241}{500} = 6,482$$
