Yechim qadamlari

2 va 4 ning eng kichik umumiy karralisi 4 ga teng. \frac{1}{2} va \frac{3}{4} ni 4 maxraj bilan kasrlarga aylantirib oling.

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

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

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

5 olish uchun 2 va 3'ni qo'shing.

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

2 ni \frac{8}{4} kasrga o‘giring.

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

\frac{5}{4} va \frac{8}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

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

-3 olish uchun 5 dan 8 ni ayirish.

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

-\frac{3}{4}\left(-8\right) ni yagona kasrga aylantiring.

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

24 hosil qilish uchun -3 va -8 ni ko'paytirish.

$$\frac{24}{4}$$

6 ni olish uchun 24 ni 4 ga bo‘ling.
