Yechim qadamlari

\frac{54}{1,4} kasrini uning surat va maxrajini 10 ga ko‘paytirish bilan kengaytiring.

$$\frac{540}{14}-0,5$$

\frac{540}{14} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{270}{7}-0,5$$

0,5 o‘nlik raqamni uning \frac{5}{10} kasrga o‘giring. \frac{5}{10} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{270}{7}-\frac{1}{2}$$

7 va 2 ning eng kichik umumiy karralisi 14 ga teng. \frac{270}{7} va \frac{1}{2} ni 14 maxraj bilan kasrlarga aylantirib oling.

$$\frac{540}{14}-\frac{7}{14}$$

\frac{540}{14} va \frac{7}{14} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{540-7}{14}$$

533 olish uchun 540 dan 7 ni ayirish.
