c-51=\frac{19}{20}
\frac{1995}{2100} ulushini 105 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
c=\frac{19}{20}+51
51 ni ikki tarafga qo’shing.
c=\frac{19}{20}+\frac{1020}{20}
51 ni \frac{1020}{20} kasrga o‘giring.
c=\frac{19+1020}{20}
\frac{19}{20} va \frac{1020}{20} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.
c=\frac{1039}{20}
