Yechim qadamlari

\frac{\frac{0\times 25}{\frac{5}{8}}}{3} ni yagona kasrga aylantiring.

$$\frac{\frac{2}{3}-\frac{0\times 25}{\frac{5}{8}\times 3}}{\frac{3\times 4+1}{4}}$$

Surat va maxrajdagi ikkala 3 ni qisqartiring.

$$\frac{\frac{2}{3}-\frac{0}{\frac{5}{8}}}{\frac{3\times 4+1}{4}}$$

Nol bo‘lmagan har qanday sonni nolga ko‘paytirsangiz, nol bo‘ladi.

$$\frac{\frac{2}{3}+0}{\frac{3\times 4+1}{4}}$$

\frac{2}{3} olish uchun \frac{2}{3} va 0'ni qo'shing.

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

12 hosil qilish uchun 3 va 4 ni ko'paytirish.

$$\frac{\frac{2}{3}}{\frac{12+1}{4}}$$

13 olish uchun 12 va 1'ni qo'shing.

$$\frac{\frac{2}{3}}{\frac{13}{4}}$$

\frac{2}{3} ni \frac{13}{4} ga bo'lish \frac{2}{3} ga k'paytirish \frac{13}{4} ga qaytarish.

$$\frac{2}{3}\times \frac{4}{13}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{2}{3} ni \frac{4}{13} ga ko‘paytiring.

$$\frac{2\times 4}{3\times 13}$$

\frac{2\times 4}{3\times 13} kasridagi ko‘paytirishlarni bajaring.

$$\frac{8}{39}$$
