Yechim qadamlari

\frac{1}{5} va \frac{3}{5} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

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

-2 olish uchun 1 dan 3 ni ayirish.

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

3 va 2 ning eng kichik umumiy karralisi 6 ga teng. \frac{4}{3} va \frac{1}{2} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$\frac{-\frac{2}{5}}{\frac{8}{6}-\frac{3}{6}}$$

\frac{8}{6} va \frac{3}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-\frac{2}{5}}{\frac{8-3}{6}}$$

5 olish uchun 8 dan 3 ni ayirish.

$$\frac{-\frac{2}{5}}{\frac{5}{6}}$$

-\frac{2}{5} ni \frac{5}{6} ga bo'lish -\frac{2}{5} ga k'paytirish \frac{5}{6} ga qaytarish.

$$-\frac{2}{5}\times \frac{6}{5}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{2}{5} ni \frac{6}{5} ga ko‘paytiring.

$$\frac{-2\times 6}{5\times 5}$$

\frac{-2\times 6}{5\times 5} kasridagi ko‘paytirishlarni bajaring.

$$\frac{-12}{25}$$

\frac{-12}{25} kasri manfiy belgini olib tashlash bilan -\frac{12}{25} sifatida qayta yozilishi mumkin.

$$-\frac{12}{25}$$

Omil

$$-\frac{12}{25} = -0,48$$
