Yechim qadamlari

4 olish uchun 5 dan 1 ni ayirish.

$$\frac{10}{4}-\frac{4}{6+8}$$

\frac{10}{4} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{5}{2}-\frac{4}{6+8}$$

14 olish uchun 6 va 8'ni qo'shing.

$$\frac{5}{2}-\frac{4}{14}$$

\frac{4}{14} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{5}{2}-\frac{2}{7}$$

2 va 7 ning eng kichik umumiy karralisi 14 ga teng. \frac{5}{2} va \frac{2}{7} ni 14 maxraj bilan kasrlarga aylantirib oling.

$$\frac{35}{14}-\frac{4}{14}$$

\frac{35}{14} va \frac{4}{14} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{35-4}{14}$$

31 olish uchun 35 dan 4 ni ayirish.

$$\frac{31}{14}$$

Omil

$$\frac{31}{2 \cdot 7} = 2\frac{3}{14} = 2,2142857142857144$$
