Yechim qadamlari

\frac{64}{10} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{-6+\frac{32}{5}}{-8}\left(-3\right)$$

-6 ni -\frac{30}{5} kasrga o‘giring.

$$\frac{-\frac{30}{5}+\frac{32}{5}}{-8}\left(-3\right)$$

-\frac{30}{5} va \frac{32}{5} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{\frac{-30+32}{5}}{-8}\left(-3\right)$$

2 olish uchun -30 va 32'ni qo'shing.

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

\frac{\frac{2}{5}}{-8} ni yagona kasrga aylantiring.

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

-40 hosil qilish uchun 5 va -8 ni ko'paytirish.

$$\frac{2}{-40}\left(-3\right)$$

\frac{2}{-40} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{1}{20}\left(-3\right)$$

-\frac{1}{20}\left(-3\right) ni yagona kasrga aylantiring.

$$\frac{-\left(-3\right)}{20}$$

3 hosil qilish uchun -1 va -3 ni ko'paytirish.

$$\frac{3}{20}$$

Omil

$$\frac{3}{2 ^ {2} \cdot 5} = 0,15$$
