$$\frac { 2 } { 3 } - \frac { 16 } { 3 } - \frac { 9 } { 2 } + 3$$

Baholash

$$-\frac{37}{6}\approx -6,166666667$$

Yechim qadamlari

\frac{2}{3} va \frac{16}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{2-16}{3}-\frac{9}{2}+3$$

-14 olish uchun 2 dan 16 ni ayirish.

$$-\frac{14}{3}-\frac{9}{2}+3$$

3 va 2 ning eng kichik umumiy karralisi 6 ga teng. -\frac{14}{3} va \frac{9}{2} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{28}{6}-\frac{27}{6}+3$$

-\frac{28}{6} va \frac{27}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-28-27}{6}+3$$

-55 olish uchun -28 dan 27 ni ayirish.

$$-\frac{55}{6}+3$$

3 ni \frac{18}{6} kasrga o‘giring.

$$-\frac{55}{6}+\frac{18}{6}$$

-\frac{55}{6} va \frac{18}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-55+18}{6}$$

-37 olish uchun -55 va 18'ni qo'shing.

$$-\frac{37}{6}$$

Omil

$$-\frac{37}{6} = -6\frac{1}{6} = -6,166666666666667$$
