1/9+2/3+1/6 eching

$$\frac { 1 } { 9 } + \frac { 2 } { 3 } + \frac { 1 } { 6 }$$

Baholash

$$\frac{17}{18}\approx 0,944444444$$

Yechim qadamlari

9 va 3 ning eng kichik umumiy karralisi 9 ga teng. \frac{1}{9} va \frac{2}{3} ni 9 maxraj bilan kasrlarga aylantirib oling.

$$\frac{1}{9}+\frac{6}{9}+\frac{1}{6}$$

\frac{1}{9} va \frac{6}{9} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{1+6}{9}+\frac{1}{6}$$

7 olish uchun 1 va 6'ni qo'shing.

$$\frac{7}{9}+\frac{1}{6}$$

9 va 6 ning eng kichik umumiy karralisi 18 ga teng. \frac{7}{9} va \frac{1}{6} ni 18 maxraj bilan kasrlarga aylantirib oling.

$$\frac{14}{18}+\frac{3}{18}$$

\frac{14}{18} va \frac{3}{18} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{14+3}{18}$$

17 olish uchun 14 va 3'ni qo'shing.

$$\frac{17}{18}$$

Omil

$$\frac{17}{2 \cdot 3 ^ {2}} = 0,9444444444444444$$
