F=-\frac{5}{7}+\frac{-15}{2}
\frac{-5}{7} kasri manfiy belgini olib tashlash bilan -\frac{5}{7} sifatida qayta yozilishi mumkin.
F=-\frac{5}{7}-\frac{15}{2}
\frac{-15}{2} kasri manfiy belgini olib tashlash bilan -\frac{15}{2} sifatida qayta yozilishi mumkin.
F=-\frac{10}{14}-\frac{105}{14}
7 va 2 ning eng kichik umumiy karralisi 14 ga teng. -\frac{5}{7} va \frac{15}{2} ni 14 maxraj bilan kasrlarga aylantirib oling.
F=\frac{-10-105}{14}
-\frac{10}{14} va \frac{105}{14} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.
F=-\frac{115}{14}
-115 olish uchun -10 dan 105 ni ayirish.
