What is the decimal form of \(\frac{7}{2}\)?\(\frac{7}{2}\) का दशमलव रूप क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 3.53.5
\(\frac{7}{2}\) means 7 divided by 2. The quotient is 3 with remainder 1, and \(\frac{1}{2}=0.5\); therefore, \(\frac{7}{2}=3+0.5=3.5\). Hence, option B is correct. Exam tip: A rational number whose denominator, in lowest form, has only factors 2 and/or 5 has a terminating decimal representation.\(\frac{7}{2}\) का अर्थ है 7 को 2 से भाग देना। 2, 7 में 3 बार जाता है और शेष 1 बचता है; \(\frac{1}{2}=0.5\), इसलिए \(\frac{7}{2}=3+0.5=3.5\)। अतः सही उत्तर B है। परीक्षा-युक्ति: हर 2 या 5 की घातों से बना हो, तो परिमेय संख्या का दशमलव रूप सांत हो सकता है।
