Yechim qadamlari

7 hosil qilish uchun 1 va 7 ni ko'paytirish.

$$175-\left(-\frac{7+2}{7}\right)\times 65\times \frac{7}{9}$$

9 olish uchun 7 va 2'ni qo'shing.

$$175-\left(-\frac{9}{7}\times 65\times \frac{7}{9}\right)$$

-\frac{9}{7}\times 65 ni yagona kasrga aylantiring.

$$175-\frac{-9\times 65}{7}\times \frac{7}{9}$$

-585 hosil qilish uchun -9 va 65 ni ko'paytirish.

$$175-\frac{-585}{7}\times \frac{7}{9}$$

\frac{-585}{7} kasri manfiy belgini olib tashlash bilan -\frac{585}{7} sifatida qayta yozilishi mumkin.

$$175-\left(-\frac{585}{7}\times \frac{7}{9}\right)$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{585}{7} ni \frac{7}{9} ga ko‘paytiring.

$$175-\frac{-585\times 7}{7\times 9}$$

Surat va maxrajdagi ikkala 7 ni qisqartiring.

$$175-\frac{-585}{9}$$

-65 ni olish uchun -585 ni 9 ga bo‘ling.

$$175-\left(-65\right)$$

-65 ning teskarisi 65 ga teng.

$$175+65$$

240 olish uchun 175 va 65'ni qo'shing.

$$240$$
