Yechim qadamlari

3 va 5 ning eng kichik umumiy karralisi 15 ga teng. \frac{1}{3} va \frac{2}{5} ni 15 maxraj bilan kasrlarga aylantirib oling.

$$\frac{\frac{5}{15}+\frac{6}{15}+\frac{1}{30}}{\frac{23}{30}}$$

\frac{5}{15} va \frac{6}{15} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{\frac{5+6}{15}+\frac{1}{30}}{\frac{23}{30}}$$

11 olish uchun 5 va 6'ni qo'shing.

$$\frac{\frac{11}{15}+\frac{1}{30}}{\frac{23}{30}}$$

15 va 30 ning eng kichik umumiy karralisi 30 ga teng. \frac{11}{15} va \frac{1}{30} ni 30 maxraj bilan kasrlarga aylantirib oling.

$$\frac{\frac{22}{30}+\frac{1}{30}}{\frac{23}{30}}$$

\frac{22}{30} va \frac{1}{30} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{\frac{22+1}{30}}{\frac{23}{30}}$$

23 olish uchun 22 va 1'ni qo'shing.

$$\frac{\frac{23}{30}}{\frac{23}{30}}$$

1 ni olish uchun \frac{23}{30} ni \frac{23}{30} ga bo‘ling.
