Yechim qadamlari

8 hosil qilish uchun 2 va 4 ni ko'paytirish.

$$\frac{8+3}{4}+\frac{1\times 14+5}{14}$$

11 olish uchun 8 va 3'ni qo'shing.

$$\frac{11}{4}+\frac{1\times 14+5}{14}$$

14 hosil qilish uchun 1 va 14 ni ko'paytirish.

$$\frac{11}{4}+\frac{14+5}{14}$$

19 olish uchun 14 va 5'ni qo'shing.

$$\frac{11}{4}+\frac{19}{14}$$

4 va 14 ning eng kichik umumiy karralisi 28 ga teng. \frac{11}{4} va \frac{19}{14} ni 28 maxraj bilan kasrlarga aylantirib oling.

$$\frac{77}{28}+\frac{38}{28}$$

\frac{77}{28} va \frac{38}{28} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{77+38}{28}$$

115 olish uchun 77 va 38'ni qo'shing.

$$\frac{115}{28}$$
