$$\frac{1}{4}=0,25$$

Yechim qadamlari

3 va 12 ning eng kichik umumiy karralisi 12 ga teng. \frac{4}{3} va \frac{13}{12} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$\frac{16}{12}-\frac{13}{12}$$

\frac{16}{12} va \frac{13}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{16-13}{12}$$

3 olish uchun 16 dan 13 ni ayirish.

$$\frac{3}{12}$$

\frac{3}{12} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
