Yechim qadamlari

3 ni \frac{12}{4} kasrga o‘giring.

$$\frac{12}{4}+\frac{1}{4}-\left(2+\frac{1}{6}\right)$$

\frac{12}{4} va \frac{1}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{12+1}{4}-\left(2+\frac{1}{6}\right)$$

13 olish uchun 12 va 1'ni qo'shing.

$$\frac{13}{4}-\left(2+\frac{1}{6}\right)$$

2 ni \frac{12}{6} kasrga o‘giring.

$$\frac{13}{4}-\left(\frac{12}{6}+\frac{1}{6}\right)$$

\frac{12}{6} va \frac{1}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{13}{4}-\frac{12+1}{6}$$

13 olish uchun 12 va 1'ni qo'shing.

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

4 va 6 ning eng kichik umumiy karralisi 12 ga teng. \frac{13}{4} va \frac{13}{6} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{39}{12}-\frac{26}{12}$$

\frac{39}{12} va \frac{26}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{39-26}{12}$$

13 olish uchun 39 dan 26 ni ayirish.

$$\frac{13}{12}$$
