Yechim qadamlari

2 daraja ko‘rsatkichini 2 ga hisoblang va 4 ni qiymatni oling.

$$-7\left(\frac{4}{3}-\frac{3}{4}+\frac{1}{2}\right)\left(-6\right)-\frac{\frac{0\times 25^{2}}{-\frac{1}{4}}}{-1}$$

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

$$-7\left(\frac{16}{12}-\frac{9}{12}+\frac{1}{2}\right)\left(-6\right)-\frac{\frac{0\times 25^{2}}{-\frac{1}{4}}}{-1}$$

\frac{16}{12} va \frac{9}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$-7\left(\frac{16-9}{12}+\frac{1}{2}\right)\left(-6\right)-\frac{\frac{0\times 25^{2}}{-\frac{1}{4}}}{-1}$$

7 olish uchun 16 dan 9 ni ayirish.

$$-7\left(\frac{7}{12}+\frac{1}{2}\right)\left(-6\right)-\frac{\frac{0\times 25^{2}}{-\frac{1}{4}}}{-1}$$

12 va 2 ning eng kichik umumiy karralisi 12 ga teng. \frac{7}{12} va \frac{1}{2} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$-7\left(\frac{7}{12}+\frac{6}{12}\right)\left(-6\right)-\frac{\frac{0\times 25^{2}}{-\frac{1}{4}}}{-1}$$

\frac{7}{12} va \frac{6}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$-7\times \frac{7+6}{12}\left(-6\right)-\frac{\frac{0\times 25^{2}}{-\frac{1}{4}}}{-1}$$

13 olish uchun 7 va 6'ni qo'shing.

$$-7\times \frac{13}{12}\left(-6\right)-\frac{\frac{0\times 25^{2}}{-\frac{1}{4}}}{-1}$$

-7\times \frac{13}{12} ni yagona kasrga aylantiring.

$$\frac{-7\times 13}{12}\left(-6\right)-\frac{\frac{0\times 25^{2}}{-\frac{1}{4}}}{-1}$$

-91 hosil qilish uchun -7 va 13 ni ko'paytirish.

$$\frac{-91}{12}\left(-6\right)-\frac{\frac{0\times 25^{2}}{-\frac{1}{4}}}{-1}$$

\frac{-91}{12} kasri manfiy belgini olib tashlash bilan -\frac{91}{12} sifatida qayta yozilishi mumkin.

$$-\frac{91}{12}\left(-6\right)-\frac{\frac{0\times 25^{2}}{-\frac{1}{4}}}{-1}$$

-\frac{91}{12}\left(-6\right) ni yagona kasrga aylantiring.

$$\frac{-91\left(-6\right)}{12}-\frac{\frac{0\times 25^{2}}{-\frac{1}{4}}}{-1}$$

546 hosil qilish uchun -91 va -6 ni ko'paytirish.

$$\frac{546}{12}-\frac{\frac{0\times 25^{2}}{-\frac{1}{4}}}{-1}$$

\frac{546}{12} ulushini 6 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{91}{2}-\frac{\frac{0\times 25^{2}}{-\frac{1}{4}}}{-1}$$

\frac{\frac{0\times 25^{2}}{-\frac{1}{4}}}{-1} ni yagona kasrga aylantiring.

$$\frac{91}{2}-\frac{0\times 25^{2}}{-\frac{1}{4}\left(-1\right)}$$

2 daraja ko‘rsatkichini 25 ga hisoblang va 625 ni qiymatni oling.

$$\frac{91}{2}-\frac{0\times 625}{-\frac{1}{4}\left(-1\right)}$$

0 hosil qilish uchun 0 va 625 ni ko'paytirish.

$$\frac{91}{2}-\frac{0}{-\frac{1}{4}\left(-1\right)}$$

\frac{1}{4} hosil qilish uchun -\frac{1}{4} va -1 ni ko'paytirish.

$$\frac{91}{2}-\frac{0}{\frac{1}{4}}$$

Nol bo‘lmagan har qanday sonni nolga ko‘paytirsangiz, nol bo‘ladi.

$$\frac{91}{2}+0$$

\frac{91}{2} olish uchun \frac{91}{2} va 0'ni qo'shing.

$$\frac{91}{2}$$

Omil

$$\frac{7 \cdot 13}{2} = 45\frac{1}{2} = 45,5$$
