Yechim qadamlari

\frac{3}{2} ni \frac{9}{2} ga bo'lish \frac{3}{2} ga k'paytirish \frac{9}{2} ga qaytarish.

$$\frac{3}{2}\times \frac{2}{9}-\frac{2}{3}\times \frac{1}{3}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{3}{2} ni \frac{2}{9} ga ko‘paytiring.

$$\frac{3\times 2}{2\times 9}-\frac{2}{3}\times \frac{1}{3}$$

Surat va maxrajdagi ikkala 2 ni qisqartiring.

$$\frac{3}{9}-\frac{2}{3}\times \frac{1}{3}$$

\frac{3}{9} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{1}{3}-\frac{2}{3}\times \frac{1}{3}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{2}{3} ni \frac{1}{3} ga ko‘paytiring.

$$\frac{1}{3}+\frac{-2}{3\times 3}$$

\frac{-2}{3\times 3} kasridagi ko‘paytirishlarni bajaring.

$$\frac{1}{3}+\frac{-2}{9}$$

\frac{-2}{9} kasri manfiy belgini olib tashlash bilan -\frac{2}{9} sifatida qayta yozilishi mumkin.

$$\frac{1}{3}-\frac{2}{9}$$

3 va 9 ning eng kichik umumiy karralisi 9 ga teng. \frac{1}{3} va \frac{2}{9} ni 9 maxraj bilan kasrlarga aylantirib oling.

$$\frac{3}{9}-\frac{2}{9}$$

\frac{3}{9} va \frac{2}{9} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{3-2}{9}$$

1 olish uchun 3 dan 2 ni ayirish.

$$\frac{1}{9}$$
