$$\frac{225}{16}=14,0625$$

Yechim qadamlari

\frac{-15}{4} kasri manfiy belgini olib tashlash bilan -\frac{15}{4} sifatida qayta yozilishi mumkin.

$$-\frac{15}{4}\times \frac{12}{5}\times \frac{-25}{16}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{15}{4} ni \frac{12}{5} ga ko‘paytiring.

$$\frac{-15\times 12}{4\times 5}\times \frac{-25}{16}$$

\frac{-15\times 12}{4\times 5} kasridagi ko‘paytirishlarni bajaring.

$$\frac{-180}{20}\times \frac{-25}{16}$$

-9 ni olish uchun -180 ni 20 ga bo‘ling.

$$-9\times \frac{-25}{16}$$

\frac{-25}{16} kasri manfiy belgini olib tashlash bilan -\frac{25}{16} sifatida qayta yozilishi mumkin.

$$-9\left(-\frac{25}{16}\right)$$

-9\left(-\frac{25}{16}\right) ni yagona kasrga aylantiring.

$$\frac{-9\left(-25\right)}{16}$$

225 hosil qilish uchun -9 va -25 ni ko'paytirish.

$$\frac{225}{16}$$

Omil

$$\frac{3 ^ {2} \cdot 5 ^ {2}}{2 ^ {4}} = 14\frac{1}{16} = 14,0625$$
