Yechim qadamlari

6 va 4 ning eng kichik umumiy karralisi 12 ga teng. \frac{7}{6} va \frac{3}{4} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\left(\frac{14}{12}-\frac{9}{12}\right)\times \frac{4}{5}$$

\frac{14}{12} va \frac{9}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{14-9}{12}\times \frac{4}{5}$$

5 olish uchun 14 dan 9 ni ayirish.

$$\frac{5}{12}\times \frac{4}{5}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{5}{12} ni \frac{4}{5} ga ko‘paytiring.

$$\frac{5\times 4}{12\times 5}$$

Surat va maxrajdagi ikkala 5 ni qisqartiring.

$$\frac{4}{12}$$

\frac{4}{12} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
