\frac{10}{9} va \frac{25}{9} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{13}{\frac{10+25}{9}+\frac{4}{9}}-\frac{15}{9}$$

35 olish uchun 10 va 25'ni qo'shing.

$$\frac{13}{\frac{35}{9}+\frac{4}{9}}-\frac{15}{9}$$

\frac{35}{9} va \frac{4}{9} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{13}{\frac{35+4}{9}}-\frac{15}{9}$$

39 olish uchun 35 va 4'ni qo'shing.

$$\frac{13}{\frac{39}{9}}-\frac{15}{9}$$

\frac{39}{9} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{13}{\frac{13}{3}}-\frac{15}{9}$$

13 ni \frac{13}{3} ga bo'lish 13 ga k'paytirish \frac{13}{3} ga qaytarish.

$$13\times \frac{3}{13}-\frac{15}{9}$$

13 va 13 ni qisqartiring.

$$3-\frac{15}{9}$$

\frac{15}{9} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$3-\frac{5}{3}$$

3 ni \frac{9}{3} kasrga o‘giring.

$$\frac{9}{3}-\frac{5}{3}$$

\frac{9}{3} va \frac{5}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{9-5}{3}$$

4 olish uchun 9 dan 5 ni ayirish.

$$\frac{4}{3}$$
