Yechim qadamlari

22 va 11 ning eng kichik umumiy karralisi 22 ga teng. \frac{7}{22} va \frac{14}{11} ni 22 maxraj bilan kasrlarga aylantirib oling.

$$\frac{\frac{7}{22}+\frac{28}{22}}{\frac{10}{33}}$$

\frac{7}{22} va \frac{28}{22} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{\frac{7+28}{22}}{\frac{10}{33}}$$

35 olish uchun 7 va 28'ni qo'shing.

$$\frac{\frac{35}{22}}{\frac{10}{33}}$$

\frac{35}{22} ni \frac{10}{33} ga bo'lish \frac{35}{22} ga k'paytirish \frac{10}{33} ga qaytarish.

$$\frac{35}{22}\times \frac{33}{10}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{35}{22} ni \frac{33}{10} ga ko‘paytiring.

$$\frac{35\times 33}{22\times 10}$$

\frac{35\times 33}{22\times 10} kasridagi ko‘paytirishlarni bajaring.

$$\frac{1155}{220}$$
