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 ayirish orqali ayiring.

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

-13 olish uchun 3 dan 16 ni ayirish.

$$-\frac{13}{12}-\frac{1}{2}+4$$

12 va 2 ning eng kichik umumiy karralisi 12 ga teng. -\frac{13}{12} va \frac{1}{2} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{13}{12}-\frac{6}{12}+4$$

-\frac{13}{12} va \frac{6}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-13-6}{12}+4$$

-19 olish uchun -13 dan 6 ni ayirish.

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

4 ni \frac{48}{12} kasrga o‘giring.

$$-\frac{19}{12}+\frac{48}{12}$$

-\frac{19}{12} va \frac{48}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-19+48}{12}$$

29 olish uchun -19 va 48'ni qo'shing.

$$\frac{29}{12}$$

Omil

$$\frac{29}{2 ^ {2} \cdot 3} = 2\frac{5}{12} = 2,4166666666666665$$
