(4/5-1/8)+(16-013) eching

$$( \frac { 4 } { 5 } - \frac { 1 } { 8 } ) + ( 16 - 013 )$$

Baholash

$$\frac{667}{40}=16,675$$

Yechim qadamlari

5 va 8 ning eng kichik umumiy karralisi 40 ga teng. \frac{4}{5} va \frac{1}{8} ni 40 maxraj bilan kasrlarga aylantirib oling.

$$\frac{32}{40}-\frac{5}{40}+16-0\times 13$$

\frac{32}{40} va \frac{5}{40} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{32-5}{40}+16-0\times 13$$

27 olish uchun 32 dan 5 ni ayirish.

$$\frac{27}{40}+16-0\times 13$$

0 hosil qilish uchun 0 va 13 ni ko'paytirish.

$$\frac{27}{40}+16-0$$

16 olish uchun 16 dan 0 ni ayirish.

$$\frac{27}{40}+16$$

16 ni \frac{640}{40} kasrga o‘giring.

$$\frac{27}{40}+\frac{640}{40}$$

\frac{27}{40} va \frac{640}{40} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{27+640}{40}$$

667 olish uchun 27 va 640'ni qo'shing.

$$\frac{667}{40}$$

Omil

$$\frac{23 \cdot 29}{2 ^ {3} \cdot 5} = 16\frac{27}{40} = 16,675$$
