52/5-43/4 eching

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

Baholash

$$\frac{13}{20}=0,65$$

Yechim qadamlari

25 hosil qilish uchun 5 va 5 ni ko'paytirish.

$$\frac{25+2}{5}-\frac{4\times 4+3}{4}$$

27 olish uchun 25 va 2'ni qo'shing.

$$\frac{27}{5}-\frac{4\times 4+3}{4}$$

16 hosil qilish uchun 4 va 4 ni ko'paytirish.

$$\frac{27}{5}-\frac{16+3}{4}$$

19 olish uchun 16 va 3'ni qo'shing.

$$\frac{27}{5}-\frac{19}{4}$$

5 va 4 ning eng kichik umumiy karralisi 20 ga teng. \frac{27}{5} va \frac{19}{4} ni 20 maxraj bilan kasrlarga aylantirib oling.

$$\frac{108}{20}-\frac{95}{20}$$

\frac{108}{20} va \frac{95}{20} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{108-95}{20}$$

13 olish uchun 108 dan 95 ni ayirish.

$$\frac{13}{20}$$

Omil

$$\frac{13}{2 ^ {2} \cdot 5} = 0,65$$
