Yechim qadamlari

1 ni \frac{2}{2} kasrga o‘giring.

$$-\frac{7}{2}-\frac{2}{2}-\left(\frac{11}{14}-\frac{3}{2}\right)-\frac{3}{14}$$

-\frac{7}{2} va \frac{2}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-7-2}{2}-\left(\frac{11}{14}-\frac{3}{2}\right)-\frac{3}{14}$$

-9 olish uchun -7 dan 2 ni ayirish.

$$-\frac{9}{2}-\left(\frac{11}{14}-\frac{3}{2}\right)-\frac{3}{14}$$

14 va 2 ning eng kichik umumiy karralisi 14 ga teng. \frac{11}{14} va \frac{3}{2} ni 14 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{9}{2}-\left(\frac{11}{14}-\frac{21}{14}\right)-\frac{3}{14}$$

\frac{11}{14} va \frac{21}{14} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$-\frac{9}{2}-\frac{11-21}{14}-\frac{3}{14}$$

-10 olish uchun 11 dan 21 ni ayirish.

$$-\frac{9}{2}-\frac{-10}{14}-\frac{3}{14}$$

\frac{-10}{14} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{9}{2}-\left(-\frac{5}{7}\right)-\frac{3}{14}$$

-\frac{5}{7} ning teskarisi \frac{5}{7} ga teng.

$$-\frac{9}{2}+\frac{5}{7}-\frac{3}{14}$$

2 va 7 ning eng kichik umumiy karralisi 14 ga teng. -\frac{9}{2} va \frac{5}{7} ni 14 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{63}{14}+\frac{10}{14}-\frac{3}{14}$$

-\frac{63}{14} va \frac{10}{14} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-63+10}{14}-\frac{3}{14}$$

-53 olish uchun -63 va 10'ni qo'shing.

$$-\frac{53}{14}-\frac{3}{14}$$

-\frac{53}{14} va \frac{3}{14} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-53-3}{14}$$

-56 olish uchun -53 dan 3 ni ayirish.

$$\frac{-56}{14}$$

-4 ni olish uchun -56 ni 14 ga bo‘ling.
