Write (0.4), \(\frac{1}{2}\), and (0.6) in correct left to right order on the number line.
A. \(0.4,\frac{1}{2},0.6\)
\(\frac{1}{2}=0.5\), इसलिए क्रम (0.4<0.5<0.6) है। तुलना से पहले भिन्न को दशमलव में बदलें। / \(\frac{1}{2}=0.5\), so the order is (0.4<0.5<0.6). Convert fractions to decimals before comparing.

To place \(\frac{11}{5}\) on the number line, between which two integers will it lie?
B. (2) और (3)(2) and (3)
\(\frac{11}{5}=2.2\), इसलिए यह (2) और (3) के बीच है। अशुद्ध भिन्न को दशमलव या मिश्रित रूप में बदलें। / \(\frac{11}{5}=2.2\), so it lies between (2) and (3). Convert an improper fraction to decimal or mixed form.

Which statement about the position of \(\sqrt{7}\) on the number line is correct?
B. यह (2) और (3) के बीच हैIt is between (2) and (3)
क्योंकि \(2^2<7<3^2\), इसलिए \(\sqrt{7}\), (2) और (3) के बीच होगा। \(\sqrt{7}\) को (7) समझना सामान्य गलती है। / Since \(2^2<7<3^2\), \(\sqrt{7}\) lies between (2) and (3). Taking \(\sqrt{7}\) as (7) is a common mistake.

Which point is closer to (3) on the number line, (3.04) or (3.4)?
A. (3.04)
(3.04) की दूरी (0.04) है और (3.4) की दूरी (0.4) है। कम दूरी वाला बिंदु अधिक पास होता है। / The distance of (3.04) is (0.04) and the distance of (3.4) is (0.4). The point with smaller distance is closer.

On the number line, which point will be to the right, (-0.8) or (-0.3)?
B. (-0.3)
(-0.3), (-0.8) से बड़ा है इसलिए वह दाईं ओर होगा। ऋणात्मक संख्याओं में (0) के पास वाली संख्या बड़ी होती है। / (-0.3) is greater than (-0.8), so it is to the right. Among negative numbers, the one closer to (0) is greater.

If \(\sqrt{n}\) lies between (4) and (5) on the number line, which value of (n) is possible?
C. (21)
\(\sqrt{n}\) के (4) और (5) के बीच होने के लिए (16<n<25) चाहिए। दिए गए विकल्पों में (21) सही है। / For \(\sqrt{n}\) to lie between (4) and (5), (16<n<25) is needed. Among the options (21) is correct.

What is the value of the midpoint between (1.2) and (1.3) on the number line?
B. (1.25)
मध्य बिंदु \(=\frac{1.2+1.3}{2}=1.25\) है। दो बिंदुओं का औसत मध्य बिंदु देता है। / The midpoint is \(\frac{1.2+1.3}{2}=1.25\). The average of two points gives the midpoint.

On the number line, which point will be to the right, \(\frac{3}{2}\) or (1.6)?
B. (1.6)
\(\frac{3}{2}=1.5\) और (1.6>1.5), इसलिए (1.6) दाईं ओर होगा। दाईं ओर संख्या का मान बढ़ता है। / \(\frac{3}{2}=1.5\) and (1.6>1.5), so (1.6) is to the right. Values increase toward the right.
