கொடுக்கப்பட்டது:

\(0.3\overline {35} \)

கணக்கீடு:

x = \(0.3\overline {35} \) → (1)

இரண்டு எண்கள் மீண்டும் மீண்டும் வருவதால், இரு பக்கங்களையும் 100 ஆல் பெருக்குவோம்.

⇒ 100x = 33.535

இதிலிருந்து (1) கழித்தால், நமக்குக் கிடைப்பது

⇒ 100x – x = 33.535 – 0.335

⇒ 99x = 33.200

⇒ x = \(\frac{33.2}{99}\) = \(\frac{332}{990}\)

எனவே, \(0.3\overline {35} \) இன் பின்னக் குறியீடு  \(\frac{332}{990}\) .
