Yechim qadamlari

\frac{2}{4} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{\frac{1}{3}+\frac{1}{2}}{\frac{1}{2}}$$

3 va 2 ning eng kichik umumiy karralisi 6 ga teng. \frac{1}{3} va \frac{1}{2} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$\frac{\frac{2}{6}+\frac{3}{6}}{\frac{1}{2}}$$

\frac{2}{6} va \frac{3}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{\frac{2+3}{6}}{\frac{1}{2}}$$

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

$$\frac{\frac{5}{6}}{\frac{1}{2}}$$

\frac{5}{6} ni \frac{1}{2} ga bo'lish \frac{5}{6} ga k'paytirish \frac{1}{2} ga qaytarish.

$$\frac{5}{6}\times 2$$

\frac{5}{6}\times 2 ni yagona kasrga aylantiring.

$$\frac{5\times 2}{6}$$

10 hosil qilish uchun 5 va 2 ni ko'paytirish.

$$\frac{10}{6}$$

\frac{10}{6} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
