728(3/100)+10/100 eching

$$728 ( \frac { 3 } { 100 } ) + \frac { 10 } { 100 }$$

Baholash

$$\frac{1097}{50}=21,94$$

Yechim qadamlari

728\times \frac{3}{100} ni yagona kasrga aylantiring.

$$\frac{728\times 3}{100}+\frac{10}{100}$$

2184 hosil qilish uchun 728 va 3 ni ko'paytirish.

$$\frac{2184}{100}+\frac{10}{100}$$

\frac{2184}{100} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{546}{25}+\frac{10}{100}$$

\frac{10}{100} ulushini 10 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{546}{25}+\frac{1}{10}$$

25 va 10 ning eng kichik umumiy karralisi 50 ga teng. \frac{546}{25} va \frac{1}{10} ni 50 maxraj bilan kasrlarga aylantirib oling.

$$\frac{1092}{50}+\frac{5}{50}$$

\frac{1092}{50} va \frac{5}{50} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{1092+5}{50}$$

1097 olish uchun 1092 va 5'ni qo'shing.

$$\frac{1097}{50}$$

Omil

$$\frac{1097}{2 \cdot 5 ^ {2}} = 21\frac{47}{50} = 21,94$$
