What is the midpoint between (x=2) and (x=-2) on the number line?
A. (0)
मध्य बिंदु (\frac{2+(-2)}{2}=0) है। विपरीत संख्याओं का मध्य हमेशा (0) होता है। / The midpoint is (\frac{2+(-2)}{2}=0). The midpoint of opposite numbers is always (0).

How many units must one move to go from (5) to (8) on the number line?
A. (3) इकाई(3) units
दूरी (|8-5|=3) इकाई है। संख्या रेखा पर अंतर ही दूरी देता है। / The distance is (|8-5|=3) units. On a number line, the difference gives the distance.

How many units must one move to go from (-6) to (-2) on the number line?
A. (4) इकाई(4) units
दूरी (|-2-(-6)|=4) इकाई है। दूरी में ऋणात्मक उत्तर नहीं आता। / The distance is (|-2-(-6)|=4) units. Distance cannot be negative.

Which point is reached by moving (2.5) units left from (0) on the number line?
A. (-2.5)
बाईं ओर जाने पर संख्या घटती है, इसलिए (0-2.5=-2.5) मिलेगा। दिशा को चिह्न से जोड़ें। / Moving left decreases the number, so (0-2.5=-2.5). Link direction with the sign.

Which point is reached by moving (3) units right from (-1) on the number line?
A. (2)
दाईं ओर जाने पर संख्या बढ़ती है, इसलिए (-1+3=2) है। चाल को जोड़ या घटाव से लिखें। / Moving right increases the number, so (-1+3=2). Write movement as addition or subtraction.

When (1.5) is compared with \(\frac{3}{2}\) on the number line, what do we get?
A. दोनों बराबर हैंboth are equal
\(\frac{3}{2}=1.5\), इसलिए दोनों एक ही बिंदु दिखाते हैं। दशमलव और भिन्न का समान मान पहचानें। / \(\frac{3}{2}=1.5\), so both show the same point. Identify equal values in decimal and fraction forms.

On the number line, \(0.333\ldots\) is considered equal to which fraction?
A. \(\frac{1}{3}\)
\(0.333\ldots=\frac{1}{3}\) एक आवर्ती दशमलव है। आवर्ती दशमलव भी संख्या रेखा पर निश्चित बिंदु दिखाते हैं। / \(0.333\ldots=\frac{1}{3}\) is a recurring decimal. Recurring decimals also represent fixed points on the number line.

On the number line, \(0.999\ldots\) is equal to which number?
A. (1)
\(0.999\ldots=1\) होता है, इसलिए दोनों एक ही बिंदु हैं। आवर्ती दशमलव को सीमित दशमलव जैसा न समझें। / \(0.999\ldots=1\), so both are the same point. Do not treat a recurring decimal like a terminating decimal.

Between which numbers will \(\sqrt{7}\) be placed on the number line?
A. (2) और (3)(2) and (3)
क्योंकि \(2^2=4\) और \(3^2=9\), इसलिए \(\sqrt{7}\) (2) और (3) के बीच है। संख्या को निकट वर्गों से घेरें। / Since \(2^2=4\) and \(3^2=9\), \(\sqrt{7}\) lies between (2) and (3). Bound the number using nearby squares.

Between which two integers will \(-\sqrt{8}\) lie on the number line?
A. (-3) और (-2)(-3) and (-2)
\(\sqrt{8}\) (2) और (3) के बीच है, इसलिए \(-\sqrt{8}\) (-3) और (-2) के बीच होगा। ऋण चिह्न दिशा बदल देता है। / \(\sqrt{8}\) lies between (2) and (3), so \(-\sqrt{8}\) lies between (-3) and (-2). The negative sign changes the direction.
