Yechim qadamlari

4 va 3 ning eng kichik umumiy karralisi 12 ga teng. \frac{1}{4} va \frac{4}{3} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{3}{12}+\frac{16}{12}-\frac{1}{2}-4$$

\frac{3}{12} va \frac{16}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{3+16}{12}-\frac{1}{2}-4$$

19 olish uchun 3 va 16'ni qo'shing.

$$\frac{19}{12}-\frac{1}{2}-4$$

12 va 2 ning eng kichik umumiy karralisi 12 ga teng. \frac{19}{12} va \frac{1}{2} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{19}{12}-\frac{6}{12}-4$$

\frac{19}{12} va \frac{6}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{19-6}{12}-4$$

13 olish uchun 19 dan 6 ni ayirish.

$$\frac{13}{12}-4$$

4 ni \frac{48}{12} kasrga o‘giring.

$$\frac{13}{12}-\frac{48}{12}$$

\frac{13}{12} va \frac{48}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{13-48}{12}$$

-35 olish uchun 13 dan 48 ni ayirish.

$$-\frac{35}{12}$$

Omil

$$-\frac{35}{12} = -2\frac{11}{12} = -2,9166666666666665$$
