\frac{10}{12} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$n\times \frac{5}{6}+\frac{4}{6}-\frac{5}{3}$$

\frac{4}{6} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$n\times \frac{5}{6}+\frac{2}{3}-\frac{5}{3}$$

\frac{2}{3} va \frac{5}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$n\times \frac{5}{6}+\frac{2-5}{3}$$

-3 olish uchun 2 dan 5 ni ayirish.

$$n\times \frac{5}{6}+\frac{-3}{3}$$

-1 ni olish uchun -3 ni 3 ga bo‘ling.
