Yechim qadamlari

15 ni \frac{5}{8} ga bo'lish 15 ga k'paytirish \frac{5}{8} ga qaytarish.

$$15\times \frac{8}{5}\left(-\frac{5}{4}\right)-\left(-8\right)$$

15\times \frac{8}{5} ni yagona kasrga aylantiring.

$$\frac{15\times 8}{5}\left(-\frac{5}{4}\right)-\left(-8\right)$$

120 hosil qilish uchun 15 va 8 ni ko'paytirish.

$$\frac{120}{5}\left(-\frac{5}{4}\right)-\left(-8\right)$$

24 ni olish uchun 120 ni 5 ga bo‘ling.

$$24\left(-\frac{5}{4}\right)-\left(-8\right)$$

24\left(-\frac{5}{4}\right) ni yagona kasrga aylantiring.

$$\frac{24\left(-5\right)}{4}-\left(-8\right)$$

-120 hosil qilish uchun 24 va -5 ni ko'paytirish.

$$\frac{-120}{4}-\left(-8\right)$$

-30 ni olish uchun -120 ni 4 ga bo‘ling.

$$-30-\left(-8\right)$$

-8 ning teskarisi 8 ga teng.

$$-30+8$$

-22 olish uchun -30 va 8'ni qo'shing.
