Yechim qadamlari

\frac{9}{6} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{3}{2}+\frac{9}{10}+2$$

2 va 10 ning eng kichik umumiy karralisi 10 ga teng. -\frac{3}{2} va \frac{9}{10} ni 10 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{15}{10}+\frac{9}{10}+2$$

-\frac{15}{10} va \frac{9}{10} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-15+9}{10}+2$$

-6 olish uchun -15 va 9'ni qo'shing.

$$\frac{-6}{10}+2$$

\frac{-6}{10} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{3}{5}+2$$

2 ni \frac{10}{5} kasrga o‘giring.

$$-\frac{3}{5}+\frac{10}{5}$$

-\frac{3}{5} va \frac{10}{5} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-3+10}{5}$$

7 olish uchun -3 va 10'ni qo'shing.

$$\frac{7}{5}$$

Omil

$$\frac{7}{5} = 1\frac{2}{5} = 1,4$$
