Yechim qadamlari

24 hosil qilish uchun 2 va 12 ni ko'paytirish.

$$-\frac{3}{4}-\frac{24+1}{12}$$

25 olish uchun 24 va 1'ni qo'shing.

$$-\frac{3}{4}-\frac{25}{12}$$

4 va 12 ning eng kichik umumiy karralisi 12 ga teng. -\frac{3}{4} va \frac{25}{12} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{9}{12}-\frac{25}{12}$$

-\frac{9}{12} va \frac{25}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-9-25}{12}$$

-34 olish uchun -9 dan 25 ni ayirish.

$$\frac{-34}{12}$$

\frac{-34}{12} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{17}{6}$$

Omil

$$-\frac{17}{6} = -2\frac{5}{6} = -2,8333333333333335$$
