Yechim qadamlari

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

$$\frac{2}{3}+\frac{4+1}{2}-\frac{5\times 4+2}{4}$$

5 olish uchun 4 va 1'ni qo'shing.

$$\frac{2}{3}+\frac{5}{2}-\frac{5\times 4+2}{4}$$

3 va 2 ning eng kichik umumiy karralisi 6 ga teng. \frac{2}{3} va \frac{5}{2} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$\frac{4}{6}+\frac{15}{6}-\frac{5\times 4+2}{4}$$

\frac{4}{6} va \frac{15}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{4+15}{6}-\frac{5\times 4+2}{4}$$

19 olish uchun 4 va 15'ni qo'shing.

$$\frac{19}{6}-\frac{5\times 4+2}{4}$$

20 hosil qilish uchun 5 va 4 ni ko'paytirish.

$$\frac{19}{6}-\frac{20+2}{4}$$

22 olish uchun 20 va 2'ni qo'shing.

$$\frac{19}{6}-\frac{22}{4}$$

\frac{22}{4} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{19}{6}-\frac{11}{2}$$

6 va 2 ning eng kichik umumiy karralisi 6 ga teng. \frac{19}{6} va \frac{11}{2} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$\frac{19}{6}-\frac{33}{6}$$

\frac{19}{6} va \frac{33}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{19-33}{6}$$

-14 olish uchun 19 dan 33 ni ayirish.

$$\frac{-14}{6}$$

\frac{-14}{6} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{7}{3}$$

Omil

$$-\frac{7}{3} = -2\frac{1}{3} = -2,3333333333333335$$
