Yechim qadamlari

4 ni \frac{16}{4} kasrga o‘giring.

$$\frac{51}{4}+\frac{16}{4}+\frac{1\times 2+1}{2}$$

\frac{51}{4} va \frac{16}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{51+16}{4}+\frac{1\times 2+1}{2}$$

67 olish uchun 51 va 16'ni qo'shing.

$$\frac{67}{4}+\frac{1\times 2+1}{2}$$

2 hosil qilish uchun 1 va 2 ni ko'paytirish.

$$\frac{67}{4}+\frac{2+1}{2}$$

3 olish uchun 2 va 1'ni qo'shing.

$$\frac{67}{4}+\frac{3}{2}$$

4 va 2 ning eng kichik umumiy karralisi 4 ga teng. \frac{67}{4} va \frac{3}{2} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$\frac{67}{4}+\frac{6}{4}$$

\frac{67}{4} va \frac{6}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{67+6}{4}$$

73 olish uchun 67 va 6'ni qo'shing.

$$\frac{73}{4}$$

Omil
