45/8+23/5 eching

$$4 \frac { 5 } { 8 } + 2 \frac { 3 } { 5 }$$

Baholash

$$\frac{289}{40}=7,225$$

Yechim qadamlari

32 hosil qilish uchun 4 va 8 ni ko'paytirish.

$$\frac{32+5}{8}+\frac{2\times 5+3}{5}$$

37 olish uchun 32 va 5'ni qo'shing.

$$\frac{37}{8}+\frac{2\times 5+3}{5}$$

10 hosil qilish uchun 2 va 5 ni ko'paytirish.

$$\frac{37}{8}+\frac{10+3}{5}$$

13 olish uchun 10 va 3'ni qo'shing.

$$\frac{37}{8}+\frac{13}{5}$$

8 va 5 ning eng kichik umumiy karralisi 40 ga teng. \frac{37}{8} va \frac{13}{5} ni 40 maxraj bilan kasrlarga aylantirib oling.

$$\frac{185}{40}+\frac{104}{40}$$

\frac{185}{40} va \frac{104}{40} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{185+104}{40}$$

289 olish uchun 185 va 104'ni qo'shing.

$$\frac{289}{40}$$

Omil

$$\frac{17 ^ {2}}{2 ^ {3} \cdot 5} = 7\frac{9}{40} = 7,225$$
