Yechim qadamlari

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

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

9 hosil qilish uchun 1 va 9 ni ko'paytirish.

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

10 olish uchun 9 va 1'ni qo'shing.

$$-\frac{1}{3}-\frac{10}{9}$$

3 va 9 ning eng kichik umumiy karralisi 9 ga teng. -\frac{1}{3} va \frac{10}{9} ni 9 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{3}{9}-\frac{10}{9}$$

-\frac{3}{9} va \frac{10}{9} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-3-10}{9}$$

-13 olish uchun -3 dan 10 ni ayirish.

$$-\frac{13}{9}$$

Omil

$$-\frac{13}{9} = -1\frac{4}{9} = -1,4444444444444444$$
