Yechim qadamlari

\frac{1}{-2} kasri manfiy belgini olib tashlash bilan -\frac{1}{2} sifatida qayta yozilishi mumkin.

$$-\frac{1}{2}-\frac{2}{\left(-2\right)^{2}}$$

2 daraja ko‘rsatkichini -2 ga hisoblang va 4 ni qiymatni oling.

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

\frac{2}{4} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

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

-\frac{1}{2} va \frac{1}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.
