41/2-14/5 eching

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

Baholash

$$\frac{27}{10}=2,7$$

Yechim qadamlari

8 hosil qilish uchun 4 va 2 ni ko'paytirish.

$$\frac{8+1}{2}-\frac{1\times 5+4}{5}$$

9 olish uchun 8 va 1'ni qo'shing.

$$\frac{9}{2}-\frac{1\times 5+4}{5}$$

5 hosil qilish uchun 1 va 5 ni ko'paytirish.

$$\frac{9}{2}-\frac{5+4}{5}$$

9 olish uchun 5 va 4'ni qo'shing.

$$\frac{9}{2}-\frac{9}{5}$$

2 va 5 ning eng kichik umumiy karralisi 10 ga teng. \frac{9}{2} va \frac{9}{5} ni 10 maxraj bilan kasrlarga aylantirib oling.

$$\frac{45}{10}-\frac{18}{10}$$

\frac{45}{10} va \frac{18}{10} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{45-18}{10}$$

27 olish uchun 45 dan 18 ni ayirish.

$$\frac{27}{10}$$

Omil

$$\frac{3 ^ {3}}{2 \cdot 5} = 2\frac{7}{10} = 2,7$$
