Yechim qadamlari

5 va 3 ning eng kichik umumiy karralisi 15 ga teng. \frac{6}{5} va \frac{1}{3} ni 15 maxraj bilan kasrlarga aylantirib oling.

$$\frac{\frac{13}{50}}{\frac{1}{2}\left(\frac{18}{15}-\frac{5}{15}\right)}$$

\frac{18}{15} va \frac{5}{15} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{\frac{13}{50}}{\frac{1}{2}\times \frac{18-5}{15}}$$

13 olish uchun 18 dan 5 ni ayirish.

$$\frac{\frac{13}{50}}{\frac{1}{2}\times \frac{13}{15}}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{1}{2} ni \frac{13}{15} ga ko‘paytiring.

$$\frac{\frac{13}{50}}{\frac{1\times 13}{2\times 15}}$$

\frac{1\times 13}{2\times 15} kasridagi ko‘paytirishlarni bajaring.

$$\frac{\frac{13}{50}}{\frac{13}{30}}$$

\frac{13}{50} ni \frac{13}{30} ga bo'lish \frac{13}{50} ga k'paytirish \frac{13}{30} ga qaytarish.

$$\frac{13}{50}\times \frac{30}{13}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{13}{50} ni \frac{30}{13} ga ko‘paytiring.

$$\frac{13\times 30}{50\times 13}$$

Surat va maxrajdagi ikkala 13 ni qisqartiring.

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

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