Yechim qadamlari

\frac{32}{6} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{16}{3}-\frac{4\times 7+5}{7}$$

28 hosil qilish uchun 4 va 7 ni ko'paytirish.

$$\frac{16}{3}-\frac{28+5}{7}$$

33 olish uchun 28 va 5'ni qo'shing.

$$\frac{16}{3}-\frac{33}{7}$$

3 va 7 ning eng kichik umumiy karralisi 21 ga teng. \frac{16}{3} va \frac{33}{7} ni 21 maxraj bilan kasrlarga aylantirib oling.

$$\frac{112}{21}-\frac{99}{21}$$

\frac{112}{21} va \frac{99}{21} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{112-99}{21}$$

13 olish uchun 112 dan 99 ni ayirish.

$$\frac{13}{21}$$
