\( -\frac{1}{2}<x\le \frac{5}{4} \) की संख्या रेखा पर सही पहचान कौन सी है?
Which is the correct identification of \( -\frac{1}{2}<x\le \frac{5}{4} \) on the number line?
Explanation opens after your attempt
A. \( -\frac{1}{2} \) खुला, \( \frac{5}{4} \) बंद, बीच में छायाOpen at \( -\frac{1}{2} \), closed at \( \frac{5}{4} \), shaded between
Concept
The left sign is ( < ), so it is open, and the right sign is \( \le \), so it is closed. The same rule applies to fractional endpoints.
Why this answer is correct
The correct answer is A. \( -\frac{1}{2} \) खुला, \( \frac{5}{4} \) बंद, बीच में छाया / Open at \( -\frac{1}{2} \), closed at \( \frac{5}{4} \), shaded between. The left sign is ( < ), so it is open, and the right sign is \( \le \), so it is closed. The same rule applies to fractional endpoints.
Exam Tip
बाईं ओर ( < ) है इसलिए खुला और दाईं ओर \( \le \) है इसलिए बंद। भिन्न सीमा पर भी वही नियम लागू होता है।
