Yechim qadamlari

2 ni \frac{8}{4} kasrga o‘giring.

$$\frac{\frac{5}{4}+\frac{8}{4}+\frac{10}{3}}{-5}$$

\frac{5}{4} va \frac{8}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{\frac{5+8}{4}+\frac{10}{3}}{-5}$$

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

$$\frac{\frac{13}{4}+\frac{10}{3}}{-5}$$

4 va 3 ning eng kichik umumiy karralisi 12 ga teng. \frac{13}{4} va \frac{10}{3} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{\frac{39}{12}+\frac{40}{12}}{-5}$$

\frac{39}{12} va \frac{40}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{\frac{39+40}{12}}{-5}$$

79 olish uchun 39 va 40'ni qo'shing.

$$\frac{\frac{79}{12}}{-5}$$

\frac{\frac{79}{12}}{-5} ni yagona kasrga aylantiring.

$$\frac{79}{12\left(-5\right)}$$

-60 hosil qilish uchun 12 va -5 ni ko'paytirish.

$$\frac{79}{-60}$$

\frac{79}{-60} kasri manfiy belgini olib tashlash bilan -\frac{79}{60} sifatida qayta yozilishi mumkin.

$$-\frac{79}{60}$$

Omil

$$-\frac{79}{60} = -1\frac{19}{60} = -1,3166666666666667$$
