Yechim qadamlari

8 ni \frac{16}{2} kasrga o‘giring.

$$\left(-\frac{1}{2}-\frac{16}{2}+\frac{3}{5}\right)\left(3+\frac{5}{8+5}\right)$$

-\frac{1}{2} va \frac{16}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\left(\frac{-1-16}{2}+\frac{3}{5}\right)\left(3+\frac{5}{8+5}\right)$$

-17 olish uchun -1 dan 16 ni ayirish.

$$\left(-\frac{17}{2}+\frac{3}{5}\right)\left(3+\frac{5}{8+5}\right)$$

2 va 5 ning eng kichik umumiy karralisi 10 ga teng. -\frac{17}{2} va \frac{3}{5} ni 10 maxraj bilan kasrlarga aylantirib oling.

$$\left(-\frac{85}{10}+\frac{6}{10}\right)\left(3+\frac{5}{8+5}\right)$$

-\frac{85}{10} va \frac{6}{10} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-85+6}{10}\left(3+\frac{5}{8+5}\right)$$

-79 olish uchun -85 va 6'ni qo'shing.

$$-\frac{79}{10}\left(3+\frac{5}{8+5}\right)$$

13 olish uchun 8 va 5'ni qo'shing.

$$-\frac{79}{10}\left(3+\frac{5}{13}\right)$$

3 ni \frac{39}{13} kasrga o‘giring.

$$-\frac{79}{10}\left(\frac{39}{13}+\frac{5}{13}\right)$$

\frac{39}{13} va \frac{5}{13} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$-\frac{79}{10}\times \frac{39+5}{13}$$

44 olish uchun 39 va 5'ni qo'shing.

$$-\frac{79}{10}\times \frac{44}{13}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{79}{10} ni \frac{44}{13} ga ko‘paytiring.

$$\frac{-79\times 44}{10\times 13}$$

\frac{-79\times 44}{10\times 13} kasridagi ko‘paytirishlarni bajaring.

$$\frac{-3476}{130}$$

\frac{-3476}{130} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{1738}{65}$$

Omil

$$-\frac{1738}{65} = -26\frac{48}{65} = -26,73846153846154$$
