Yechim qadamlari

8 ni \frac{40}{5} kasrga o‘giring.

$$\frac{2}{3}-8\left(4-6\left(\frac{2}{5}-\frac{40}{5}\right)\right)$$

\frac{2}{5} va \frac{40}{5} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{2}{3}-8\left(4-6\times \frac{2-40}{5}\right)$$

-38 olish uchun 2 dan 40 ni ayirish.

$$\frac{2}{3}-8\left(4-6\left(-\frac{38}{5}\right)\right)$$

6\left(-\frac{38}{5}\right) ni yagona kasrga aylantiring.

$$\frac{2}{3}-8\left(4-\frac{6\left(-38\right)}{5}\right)$$

-228 hosil qilish uchun 6 va -38 ni ko'paytirish.

$$\frac{2}{3}-8\left(4-\frac{-228}{5}\right)$$

\frac{-228}{5} kasri manfiy belgini olib tashlash bilan -\frac{228}{5} sifatida qayta yozilishi mumkin.

$$\frac{2}{3}-8\left(4-\left(-\frac{228}{5}\right)\right)$$

-\frac{228}{5} ning teskarisi \frac{228}{5} ga teng.

$$\frac{2}{3}-8\left(4+\frac{228}{5}\right)$$

4 ni \frac{20}{5} kasrga o‘giring.

$$\frac{2}{3}-8\left(\frac{20}{5}+\frac{228}{5}\right)$$

\frac{20}{5} va \frac{228}{5} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{2}{3}-8\times \frac{20+228}{5}$$

248 olish uchun 20 va 228'ni qo'shing.

$$\frac{2}{3}-8\times \frac{248}{5}$$

8\times \frac{248}{5} ni yagona kasrga aylantiring.

$$\frac{2}{3}-\frac{8\times 248}{5}$$

1984 hosil qilish uchun 8 va 248 ni ko'paytirish.

$$\frac{2}{3}-\frac{1984}{5}$$

3 va 5 ning eng kichik umumiy karralisi 15 ga teng. \frac{2}{3} va \frac{1984}{5} ni 15 maxraj bilan kasrlarga aylantirib oling.

$$\frac{10}{15}-\frac{5952}{15}$$

\frac{10}{15} va \frac{5952}{15} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{10-5952}{15}$$

-5942 olish uchun 10 dan 5952 ni ayirish.

$$-\frac{5942}{15}$$

Omil

$$-\frac{5942}{15} = -396\frac{2}{15} = -396,1333333333333$$
