-\frac{1}{2} ning teskarisi \frac{1}{2} ga teng.

$$\frac{1}{2}\times 4\left(-\frac{2}{3}\right)\left(-12\right)$$

\frac{4}{2} hosil qilish uchun \frac{1}{2} va 4 ni ko'paytirish.

$$\frac{4}{2}\left(-\frac{2}{3}\right)\left(-12\right)$$

2 ni olish uchun 4 ni 2 ga bo‘ling.

$$2\left(-\frac{2}{3}\right)\left(-12\right)$$

2\left(-\frac{2}{3}\right) ni yagona kasrga aylantiring.

$$\frac{2\left(-2\right)}{3}\left(-12\right)$$

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

$$\frac{-4}{3}\left(-12\right)$$

\frac{-4}{3} kasri manfiy belgini olib tashlash bilan -\frac{4}{3} sifatida qayta yozilishi mumkin.

$$-\frac{4}{3}\left(-12\right)$$
