Yechim qadamlari

\frac{6}{-18} ulushini 6 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{1}{3}-\frac{3}{2\left(-18\right)}$$

-36 hosil qilish uchun 2 va -18 ni ko'paytirish.

$$-\frac{1}{3}-\frac{3}{-36}$$

\frac{3}{-36} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{1}{3}-\left(-\frac{1}{12}\right)$$

-\frac{1}{12} ning teskarisi \frac{1}{12} ga teng.

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

3 va 12 ning eng kichik umumiy karralisi 12 ga teng. -\frac{1}{3} va \frac{1}{12} ni 12 maxraj bilan kasrlarga aylantirib oling.

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

-\frac{4}{12} va \frac{1}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

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

-3 olish uchun -4 va 1'ni qo'shing.

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

\frac{-3}{12} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{1}{4}$$

Omil

$$-\frac{1}{4} = -0,25$$
