Yechim qadamlari

\frac{5}{-4} kasri manfiy belgini olib tashlash bilan -\frac{5}{4} sifatida qayta yozilishi mumkin.

$$-63-\left(-\frac{5}{4}\right)-1+\frac{9}{-3}$$

-\frac{5}{4} ning teskarisi \frac{5}{4} ga teng.

$$-63+\frac{5}{4}-1+\frac{9}{-3}$$

-63 ni -\frac{252}{4} kasrga o‘giring.

$$-\frac{252}{4}+\frac{5}{4}-1+\frac{9}{-3}$$

-\frac{252}{4} va \frac{5}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-252+5}{4}-1+\frac{9}{-3}$$

-247 olish uchun -252 va 5'ni qo'shing.

$$-\frac{247}{4}-1+\frac{9}{-3}$$

1 ni \frac{4}{4} kasrga o‘giring.

$$-\frac{247}{4}-\frac{4}{4}+\frac{9}{-3}$$

-\frac{247}{4} va \frac{4}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-247-4}{4}+\frac{9}{-3}$$

-251 olish uchun -247 dan 4 ni ayirish.

$$-\frac{251}{4}+\frac{9}{-3}$$

-3 ni olish uchun 9 ni -3 ga bo‘ling.

$$-\frac{251}{4}-3$$

3 ni \frac{12}{4} kasrga o‘giring.

$$-\frac{251}{4}-\frac{12}{4}$$

-\frac{251}{4} va \frac{12}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-251-12}{4}$$

-263 olish uchun -251 dan 12 ni ayirish.

$$-\frac{263}{4}$$

Omil

$$-\frac{263}{4} = -65\frac{3}{4} = -65,75$$
