$$-\frac{23}{4}+\frac{13}{3}-\frac{6\times 72+54}{72}$$

4 va 3 ning eng kichik umumiy karralisi 12 ga teng. -\frac{23}{4} va \frac{13}{3} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{69}{12}+\frac{52}{12}-\frac{6\times 72+54}{72}$$

-\frac{69}{12} va \frac{52}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-69+52}{12}-\frac{6\times 72+54}{72}$$

-17 olish uchun -69 va 52'ni qo'shing.

$$-\frac{17}{12}-\frac{6\times 72+54}{72}$$

432 hosil qilish uchun 6 va 72 ni ko'paytirish.

$$-\frac{17}{12}-\frac{432+54}{72}$$

486 olish uchun 432 va 54'ni qo'shing.

$$-\frac{17}{12}-\frac{486}{72}$$

\frac{486}{72} ulushini 18 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{17}{12}-\frac{27}{4}$$

12 va 4 ning eng kichik umumiy karralisi 12 ga teng. -\frac{17}{12} va \frac{27}{4} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{17}{12}-\frac{81}{12}$$

-\frac{17}{12} va \frac{81}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-17-81}{12}$$

-98 olish uchun -17 dan 81 ni ayirish.

$$\frac{-98}{12}$$

\frac{-98}{12} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
