Yechim qadamlari

3 hosil qilish uchun 1 va 3 ni ko'paytirish.

$$\frac{\frac{1}{2}\times \frac{-\frac{3+2}{3}}{3}}{\frac{3}{4}}$$

5 olish uchun 3 va 2'ni qo'shing.

$$\frac{\frac{1}{2}\times \frac{-\frac{5}{3}}{3}}{\frac{3}{4}}$$

\frac{-\frac{5}{3}}{3} ni yagona kasrga aylantiring.

$$\frac{\frac{1}{2}\times \frac{-5}{3\times 3}}{\frac{3}{4}}$$

9 hosil qilish uchun 3 va 3 ni ko'paytirish.

$$\frac{\frac{1}{2}\times \frac{-5}{9}}{\frac{3}{4}}$$

\frac{-5}{9} kasri manfiy belgini olib tashlash bilan -\frac{5}{9} sifatida qayta yozilishi mumkin.

$$\frac{\frac{1}{2}\left(-\frac{5}{9}\right)}{\frac{3}{4}}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{1}{2} ni -\frac{5}{9} ga ko‘paytiring.

$$\frac{\frac{1\left(-5\right)}{2\times 9}}{\frac{3}{4}}$$

\frac{1\left(-5\right)}{2\times 9} kasridagi ko‘paytirishlarni bajaring.

$$\frac{\frac{-5}{18}}{\frac{3}{4}}$$

\frac{-5}{18} kasri manfiy belgini olib tashlash bilan -\frac{5}{18} sifatida qayta yozilishi mumkin.

$$\frac{-\frac{5}{18}}{\frac{3}{4}}$$

-\frac{5}{18} ni \frac{3}{4} ga bo'lish -\frac{5}{18} ga k'paytirish \frac{3}{4} ga qaytarish.

$$-\frac{5}{18}\times \frac{4}{3}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{5}{18} ni \frac{4}{3} ga ko‘paytiring.

$$\frac{-5\times 4}{18\times 3}$$

\frac{-5\times 4}{18\times 3} kasridagi ko‘paytirishlarni bajaring.

$$\frac{-20}{54}$$

\frac{-20}{54} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
