-\frac{3}{7}+\frac{28}{7}=-\frac{1}{3}
4 ni \frac{28}{7} kasrga o‘giring.
\frac{-3+28}{7}=-\frac{1}{3}
-\frac{3}{7} va \frac{28}{7} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.
\frac{25}{7}=-\frac{1}{3}
25 olish uchun -3 va 28'ni qo'shing.
\frac{75}{21}=-\frac{7}{21}
7 va 3 ning eng kichik umumiy karralisi 21 ga teng. \frac{25}{7} va -\frac{1}{3} ni 21 maxraj bilan kasrlarga aylantirib oling.
\text{false}
\frac{75}{21} va -\frac{7}{21} ni taqqoslang.
