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

Baholash

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

Yechim qadamlari

-2 ni olish uchun -4 ni 2 ga bo‘ling.

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

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

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

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

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

-2 ni -\frac{4}{2} kasrga o‘giring.

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

-\frac{4}{2} va \frac{1}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

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

-3 olish uchun -4 va 1'ni qo'shing.

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

Omil

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