Yechim qadamlari

4 ni \frac{20}{5} kasrga o‘giring.

$$\frac{\frac{20}{5}-\frac{2}{5}}{\frac{5}{9}-\frac{2}{6}}$$

\frac{20}{5} va \frac{2}{5} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{\frac{20-2}{5}}{\frac{5}{9}-\frac{2}{6}}$$

18 olish uchun 20 dan 2 ni ayirish.

$$\frac{\frac{18}{5}}{\frac{5}{9}-\frac{2}{6}}$$

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

$$\frac{\frac{18}{5}}{\frac{5}{9}-\frac{1}{3}}$$

9 va 3 ning eng kichik umumiy karralisi 9 ga teng. \frac{5}{9} va \frac{1}{3} ni 9 maxraj bilan kasrlarga aylantirib oling.

$$\frac{\frac{18}{5}}{\frac{5}{9}-\frac{3}{9}}$$

\frac{5}{9} va \frac{3}{9} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{\frac{18}{5}}{\frac{5-3}{9}}$$

2 olish uchun 5 dan 3 ni ayirish.

$$\frac{\frac{18}{5}}{\frac{2}{9}}$$

\frac{18}{5} ni \frac{2}{9} ga bo'lish \frac{18}{5} ga k'paytirish \frac{2}{9} ga qaytarish.

$$\frac{18}{5}\times \frac{9}{2}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{18}{5} ni \frac{9}{2} ga ko‘paytiring.

$$\frac{18\times 9}{5\times 2}$$

\frac{18\times 9}{5\times 2} kasridagi ko‘paytirishlarni bajaring.

$$\frac{162}{10}$$

\frac{162}{10} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{81}{5}$$
