Yechim qadamlari

2 daraja ko‘rsatkichini \frac{2}{3} ga hisoblang va \frac{4}{9} ni qiymatni oling.

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

1 ni \frac{9}{9} kasrga o‘giring.

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

\frac{9}{9} va \frac{4}{9} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$-\frac{3}{5}\times \frac{9-4}{9}$$

5 olish uchun 9 dan 4 ni ayirish.

$$-\frac{3}{5}\times \frac{5}{9}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{3}{5} ni \frac{5}{9} ga ko‘paytiring.

$$\frac{-3\times 5}{5\times 9}$$

Surat va maxrajdagi ikkala 5 ni qisqartiring.

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

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

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

Omil

$$-\frac{1}{3} = -0,3333333333333333$$
