Bhai, yeh ek dum simple rule hai! Agar denominator ke prime factors sirf 2 ya 5 hain, toh decimal terminate karega. 3125 = 5 x 5 x 5 x 5 x 5, bas 5 hai, isliye yeh terminate hoga! Yeh humne class mein abhi seekha hai, fractions chapter mein. Main bhi apni sister ke school fees ke hisaab karne jaise sochta hoon – har baar pura divide ho jaana chahiye, bachat karna!
