Yechim qadamlari

\frac{-4}{9} kasri manfiy belgini olib tashlash bilan -\frac{4}{9} sifatida qayta yozilishi mumkin.

$$-\frac{4}{9}\times \frac{3}{5}\times \frac{-9}{10}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{4}{9} ni \frac{3}{5} ga ko‘paytiring.

$$\frac{-4\times 3}{9\times 5}\times \frac{-9}{10}$$

\frac{-4\times 3}{9\times 5} kasridagi ko‘paytirishlarni bajaring.
