1+2-1-2/3-2/3+1 eching

$$1 + 2 - 1 - \frac { 2 } { 3 } - \frac { 2 } { 3 } + 1$$

Baholash

$$\frac{5}{3}\approx 1,666666667$$

Yechim qadamlari

3 olish uchun 1 va 2'ni qo'shing.

$$3-1-\frac{2}{3}-\frac{2}{3}+1$$

2 olish uchun 3 dan 1 ni ayirish.

$$2-\frac{2}{3}-\frac{2}{3}+1$$

2 ni \frac{6}{3} kasrga o‘giring.

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

\frac{6}{3} va \frac{2}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

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

4 olish uchun 6 dan 2 ni ayirish.

$$\frac{4}{3}-\frac{2}{3}+1$$

\frac{4}{3} va \frac{2}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{4-2}{3}+1$$

2 olish uchun 4 dan 2 ni ayirish.

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

1 ni \frac{3}{3} kasrga o‘giring.

$$\frac{2}{3}+\frac{3}{3}$$

\frac{2}{3} va \frac{3}{3} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{2+3}{3}$$

5 olish uchun 2 va 3'ni qo'shing.

$$\frac{5}{3}$$

Omil

$$\frac{5}{3} = 1\frac{2}{3} = 1,6666666666666667$$
