212/3-41/5 eching

$$21 \frac { 2 } { 3 } - 4 \frac { 1 } { 5 }$$

Baholash

$$\frac{262}{15}\approx 17,466666667$$

Yechim qadamlari

63 hosil qilish uchun 21 va 3 ni ko'paytirish.

$$\frac{63+2}{3}-\frac{4\times 5+1}{5}$$

65 olish uchun 63 va 2'ni qo'shing.

$$\frac{65}{3}-\frac{4\times 5+1}{5}$$

20 hosil qilish uchun 4 va 5 ni ko'paytirish.

$$\frac{65}{3}-\frac{20+1}{5}$$

21 olish uchun 20 va 1'ni qo'shing.

$$\frac{65}{3}-\frac{21}{5}$$

3 va 5 ning eng kichik umumiy karralisi 15 ga teng. \frac{65}{3} va \frac{21}{5} ni 15 maxraj bilan kasrlarga aylantirib oling.

$$\frac{325}{15}-\frac{63}{15}$$

\frac{325}{15} va \frac{63}{15} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{325-63}{15}$$

262 olish uchun 325 dan 63 ni ayirish.

$$\frac{262}{15}$$

Omil

$$\frac{2 \cdot 131}{3 \cdot 5} = 17\frac{7}{15} = 17,466666666666665$$
