Yechim qadamlari

Surat va maxrajdagi ikkala n ni qisqartiring.

$$\left(\frac{1}{3}-\frac{3n}{n}\right)\times \frac{3n}{n-3n}$$

Surat va maxrajdagi ikkala n ni qisqartiring.

$$\left(\frac{1}{3}-3\right)\times \frac{3n}{n-3n}$$

3 ni \frac{9}{3} kasrga o‘giring.

$$\left(\frac{1}{3}-\frac{9}{3}\right)\times \frac{3n}{n-3n}$$

\frac{1}{3} va \frac{9}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{1-9}{3}\times \frac{3n}{n-3n}$$

-8 olish uchun 1 dan 9 ni ayirish.

$$-\frac{8}{3}\times \frac{3n}{n-3n}$$

-2n ni olish uchun n va -3n ni birlashtirish.

$$-\frac{8}{3}\times \frac{3n}{-2n}$$

Surat va maxrajdagi ikkala n ni qisqartiring.

$$-\frac{8}{3}\times \frac{3}{-2}$$

\frac{3}{-2} kasri manfiy belgini olib tashlash bilan -\frac{3}{2} sifatida qayta yozilishi mumkin.

$$-\frac{8}{3}\left(-\frac{3}{2}\right)$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{8}{3} ni -\frac{3}{2} ga ko‘paytiring.

$$\frac{-8\left(-3\right)}{3\times 2}$$

\frac{-8\left(-3\right)}{3\times 2} kasridagi ko‘paytirishlarni bajaring.

$$\frac{24}{6}$$

4 ni olish uchun 24 ni 6 ga bo‘ling.
