Yechim qadamlari

\frac{75}{6} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{5}{26}-\left(-\frac{25}{2}\right)$$

-\frac{25}{2} ning teskarisi \frac{25}{2} ga teng.

$$-\frac{5}{26}+\frac{25}{2}$$

26 va 2 ning eng kichik umumiy karralisi 26 ga teng. -\frac{5}{26} va \frac{25}{2} ni 26 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{5}{26}+\frac{325}{26}$$

-\frac{5}{26} va \frac{325}{26} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-5+325}{26}$$

320 olish uchun -5 va 325'ni qo'shing.

$$\frac{320}{26}$$

\frac{320}{26} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{160}{13}$$

Omil

$$\frac{2 ^ {5} \cdot 5}{13} = 12\frac{4}{13} = 12,307692307692308$$
