Yechim qadamlari

1 ni \frac{4}{4} kasrga o‘giring.

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

\frac{3}{4} va \frac{4}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

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

-1 olish uchun 3 dan 4 ni ayirish.

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

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{1}{2} ni -\frac{1}{4} ga ko‘paytiring.

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

\frac{1\left(-1\right)}{2\times 4} kasridagi ko‘paytirishlarni bajaring.

$$\frac{3}{4}+\frac{-1}{8}$$

\frac{-1}{8} kasri manfiy belgini olib tashlash bilan -\frac{1}{8} sifatida qayta yozilishi mumkin.

$$\frac{3}{4}-\frac{1}{8}$$

4 va 8 ning eng kichik umumiy karralisi 8 ga teng. \frac{3}{4} va \frac{1}{8} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\frac{6}{8}-\frac{1}{8}$$

\frac{6}{8} va \frac{1}{8} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{6-1}{8}$$

5 olish uchun 6 dan 1 ni ayirish.

$$\frac{5}{8}$$
