Yechim qadamlari

\frac{\frac{2}{3}}{-4} ni yagona kasrga aylantiring.

$$\frac{\frac{2}{3\left(-4\right)}-\frac{1}{4}\times 0\times 4}{\left(\frac{1}{3}\right)^{2}}-\left(-2\right)$$

-12 hosil qilish uchun 3 va -4 ni ko'paytirish.

$$\frac{\frac{2}{-12}-\frac{1}{4}\times 0\times 4}{\left(\frac{1}{3}\right)^{2}}-\left(-2\right)$$

\frac{2}{-12} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{-\frac{1}{6}-\frac{1}{4}\times 0\times 4}{\left(\frac{1}{3}\right)^{2}}-\left(-2\right)$$

0 hosil qilish uchun \frac{1}{4} va 0 ni ko'paytirish.

$$\frac{-\frac{1}{6}-0\times 4}{\left(\frac{1}{3}\right)^{2}}-\left(-2\right)$$

0 hosil qilish uchun 0 va 4 ni ko'paytirish.

$$\frac{-\frac{1}{6}-0}{\left(\frac{1}{3}\right)^{2}}-\left(-2\right)$$

-\frac{1}{6} olish uchun -\frac{1}{6} dan 0 ni ayirish.

$$\frac{-\frac{1}{6}}{\left(\frac{1}{3}\right)^{2}}-\left(-2\right)$$

2 daraja ko‘rsatkichini \frac{1}{3} ga hisoblang va \frac{1}{9} ni qiymatni oling.

$$\frac{-\frac{1}{6}}{\frac{1}{9}}-\left(-2\right)$$

-\frac{1}{6} ni \frac{1}{9} ga bo'lish -\frac{1}{6} ga k'paytirish \frac{1}{9} ga qaytarish.

$$-\frac{1}{6}\times 9-\left(-2\right)$$

-\frac{1}{6}\times 9 ni yagona kasrga aylantiring.

$$\frac{-9}{6}-\left(-2\right)$$

\frac{-9}{6} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

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

-2 ning teskarisi 2 ga teng.

$$-\frac{3}{2}+2$$

2 ni \frac{4}{2} kasrga o‘giring.

$$-\frac{3}{2}+\frac{4}{2}$$

-\frac{3}{2} va \frac{4}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-3+4}{2}$$

1 olish uchun -3 va 4'ni qo'shing.

$$\frac{1}{2}$$

Omil

$$\frac{1}{2} = 0,5$$
