6/7+(5/14-6/7) eching

$$\frac { 6 } { 7 } + ( \frac { 5 } { 14 } - \frac { 6 } { 7 } )$$

Baholash

$$\frac{5}{14}\approx 0,357142857$$

Yechim qadamlari

7 va 14 ning eng kichik umumiy karralisi 14 ga teng. \frac{6}{7} va \frac{5}{14} ni 14 maxraj bilan kasrlarga aylantirib oling.

$$\frac{12}{14}+\frac{5}{14}-\frac{6}{7}$$

\frac{12}{14} va \frac{5}{14} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{12+5}{14}-\frac{6}{7}$$

17 olish uchun 12 va 5'ni qo'shing.

$$\frac{17}{14}-\frac{6}{7}$$

14 va 7 ning eng kichik umumiy karralisi 14 ga teng. \frac{17}{14} va \frac{6}{7} ni 14 maxraj bilan kasrlarga aylantirib oling.

$$\frac{17}{14}-\frac{12}{14}$$

\frac{17}{14} va \frac{12}{14} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{17-12}{14}$$

5 olish uchun 17 dan 12 ni ayirish.

$$\frac{5}{14}$$

Omil

$$\frac{5}{2 \cdot 7} = 0,35714285714285715$$
