\frac{84}{20}-\frac{12,5}{5}
\frac{8,4}{2} kasrini uning surat va maxrajini 10 ga ko‘paytirish bilan kengaytiring.
\frac{21}{5}-\frac{12,5}{5}
\frac{84}{20} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
\frac{21}{5}-\frac{125}{50}
\frac{12,5}{5} kasrini uning surat va maxrajini 10 ga ko‘paytirish bilan kengaytiring.
\frac{21}{5}-\frac{5}{2}
\frac{125}{50} ulushini 25 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
\frac{42}{10}-\frac{25}{10}
5 va 2 ning eng kichik umumiy karralisi 10 ga teng. \frac{21}{5} va \frac{5}{2} ni 10 maxraj bilan kasrlarga aylantirib oling.
\frac{42-25}{10}
\frac{42}{10} va \frac{25}{10} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.
\frac{17}{10}
17 olish uchun 42 dan 25 ni ayirish.
