Yechim qadamlari

24 hosil qilish uchun 6 va 4 ni ko'paytirish.

$$2\left(\frac{24+1}{4}-\frac{4\times 6+1}{6}\right)\times \frac{2}{5}$$

25 olish uchun 24 va 1'ni qo'shing.

$$2\left(\frac{25}{4}-\frac{4\times 6+1}{6}\right)\times \frac{2}{5}$$

24 hosil qilish uchun 4 va 6 ni ko'paytirish.

$$2\left(\frac{25}{4}-\frac{24+1}{6}\right)\times \frac{2}{5}$$

25 olish uchun 24 va 1'ni qo'shing.

$$2\left(\frac{25}{4}-\frac{25}{6}\right)\times \frac{2}{5}$$

4 va 6 ning eng kichik umumiy karralisi 12 ga teng. \frac{25}{4} va \frac{25}{6} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$2\left(\frac{75}{12}-\frac{50}{12}\right)\times \frac{2}{5}$$

\frac{75}{12} va \frac{50}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$2\times \frac{75-50}{12}\times \frac{2}{5}$$

25 olish uchun 75 dan 50 ni ayirish.

$$2\times \frac{25}{12}\times \frac{2}{5}$$

2\times \frac{25}{12} ni yagona kasrga aylantiring.

$$\frac{2\times 25}{12}\times \frac{2}{5}$$

50 hosil qilish uchun 2 va 25 ni ko'paytirish.

$$\frac{50}{12}\times \frac{2}{5}$$

\frac{50}{12} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{25}{6}\times \frac{2}{5}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{25}{6} ni \frac{2}{5} ga ko‘paytiring.

$$\frac{25\times 2}{6\times 5}$$

\frac{25\times 2}{6\times 5} kasridagi ko‘paytirishlarni bajaring.

$$\frac{50}{30}$$

\frac{50}{30} ulushini 10 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

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

Omil

$$\frac{5}{3} = 1\frac{2}{3} = 1,6666666666666667$$
