Yechim qadamlari

4 hosil qilish uchun 1 va 4 ni ko'paytirish.

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

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

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

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{2}{3} ni \frac{5}{4} ga ko‘paytiring.

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

\frac{2\times 5}{3\times 4} kasridagi ko‘paytirishlarni bajaring.

$$\frac{10}{12}-\frac{\frac{1\times 5+1}{5}}{2}$$

\frac{10}{12} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{5}{6}-\frac{\frac{1\times 5+1}{5}}{2}$$

\frac{\frac{1\times 5+1}{5}}{2} ni yagona kasrga aylantiring.

$$\frac{5}{6}-\frac{1\times 5+1}{5\times 2}$$

5 hosil qilish uchun 1 va 5 ni ko'paytirish.

$$\frac{5}{6}-\frac{5+1}{5\times 2}$$

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

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

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

$$\frac{5}{6}-\frac{6}{10}$$

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

$$\frac{5}{6}-\frac{3}{5}$$

6 va 5 ning eng kichik umumiy karralisi 30 ga teng. \frac{5}{6} va \frac{3}{5} ni 30 maxraj bilan kasrlarga aylantirib oling.

$$\frac{25}{30}-\frac{18}{30}$$

\frac{25}{30} va \frac{18}{30} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{25-18}{30}$$

7 olish uchun 25 dan 18 ni ayirish.

$$\frac{7}{30}$$

Omil

$$\frac{7}{2 \cdot 3 \cdot 5} = 0,23333333333333334$$
