Yechim qadamlari

12 ni \frac{\frac{1}{8}-\frac{1}{4}}{\frac{1}{18}-\frac{1}{9}} ga bo'lish 12 ga k'paytirish \frac{\frac{1}{8}-\frac{1}{4}}{\frac{1}{18}-\frac{1}{9}} ga qaytarish.

$$\frac{12\left(\frac{1}{18}-\frac{1}{9}\right)}{\frac{1}{8}-\frac{1}{4}}$$

18 va 9 ning eng kichik umumiy karralisi 18 ga teng. \frac{1}{18} va \frac{1}{9} ni 18 maxraj bilan kasrlarga aylantirib oling.

$$\frac{12\left(\frac{1}{18}-\frac{2}{18}\right)}{\frac{1}{8}-\frac{1}{4}}$$

\frac{1}{18} va \frac{2}{18} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{12\times \frac{1-2}{18}}{\frac{1}{8}-\frac{1}{4}}$$

-1 olish uchun 1 dan 2 ni ayirish.

$$\frac{12\left(-\frac{1}{18}\right)}{\frac{1}{8}-\frac{1}{4}}$$

12\left(-\frac{1}{18}\right) ni yagona kasrga aylantiring.

$$\frac{\frac{12\left(-1\right)}{18}}{\frac{1}{8}-\frac{1}{4}}$$

-12 hosil qilish uchun 12 va -1 ni ko'paytirish.

$$\frac{\frac{-12}{18}}{\frac{1}{8}-\frac{1}{4}}$$

\frac{-12}{18} ulushini 6 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{-\frac{2}{3}}{\frac{1}{8}-\frac{1}{4}}$$

8 va 4 ning eng kichik umumiy karralisi 8 ga teng. \frac{1}{8} va \frac{1}{4} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\frac{-\frac{2}{3}}{\frac{1}{8}-\frac{2}{8}}$$

\frac{1}{8} va \frac{2}{8} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-\frac{2}{3}}{\frac{1-2}{8}}$$

-1 olish uchun 1 dan 2 ni ayirish.

$$\frac{-\frac{2}{3}}{-\frac{1}{8}}$$

-\frac{2}{3} ni -\frac{1}{8} ga bo'lish -\frac{2}{3} ga k'paytirish -\frac{1}{8} ga qaytarish.

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

-\frac{2}{3}\left(-8\right) ni yagona kasrga aylantiring.

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

16 hosil qilish uchun -2 va -8 ni ko'paytirish.

$$\frac{16}{3}$$
