If (A=-4.6) and (B=2.9) on the number line, what is the length of (AB)?
B. (7.5)
दूरी ( |2.9-(-4.6)|=7.5 ) है। दूरी हमेशा धनात्मक माप होती है। / The distance is ( |2.9-(-4.6)|=7.5 ). Distance is always a positive measure.

How should \( \frac{11}{12} \) be correctly understood between (0) and (1) on the number line?
B. (0) से (1) तक (12) बराबर भागों में (11)वाँ बिंदुThe (11)th point among (12) equal parts from (0) to (1)
\( \frac{11}{12} \) का अर्थ (12) बराबर भागों में (11) भाग है। हर बराबर भागों की संख्या बताता है। / \( \frac{11}{12} \) means (11) parts out of (12) equal parts. The denominator gives the number of equal parts.

If \( |x-4|=\frac{7}{2} \), what are the possible values of (x) on the number line?
A. \( \frac{1}{2} \) और \( \frac{15}{2} \)\( \frac{1}{2} \) and \( \frac{15}{2} \)
\( |x-4|=\frac{7}{2} \) का अर्थ (x) की (4) से दूरी \( \frac{7}{2} \) है। दोनों दिशाओं में \( \frac{1}{2} \) और \( \frac{15}{2} \) मिलते हैं। / \( |x-4|=\frac{7}{2} \) means (x) is at distance \( \frac{7}{2} \) from (4). Moving both directions gives \( \frac{1}{2} \) and \( \frac{15}{2} \).

What is the simplified form of \( \sqrt{2}+\sqrt{8} \) on the number line?
A. \(3\sqrt{2}\)
\( \sqrt{8}=2\sqrt{2} \), इसलिए \( \sqrt{2}+\sqrt{8}=3\sqrt{2} \)। समान मूलों को ही जोड़ा जाता है। / \( \sqrt{8}=2\sqrt{2} \), so \( \sqrt{2}+\sqrt{8}=3\sqrt{2} \). Only like radicals can be added.

Which decimal is equal to \( -\frac{7}{8} \) on the number line?
A. ( -0.875 )
\( \frac{7}{8}=0.875 \), इसलिए \( -\frac{7}{8}=-0.875 \)। ऋण चिह्न को दशमलव में भी बनाए रखें। / \( \frac{7}{8}=0.875 \), so \( -\frac{7}{8}=-0.875 \). Keep the negative sign in the decimal form.

If (M) is the midpoint of \(-\frac{5}{3}\) and \( \frac{7}{3} \) on the number line, what is (M)?
A. \( \frac{1}{3} \)
मध्य बिंदु \( \frac{-\frac{5}{3}+\frac{7}{3}}{2}=\frac{1}{3} \) है। मध्य बिंदु के लिए औसत लें। / The midpoint is \( \frac{-\frac{5}{3}+\frac{7}{3}}{2}=\frac{1}{3} \). Take the average to find the midpoint.

Which is farther right on the number line between \( \sqrt{5} \) and \( \frac{9}{4} \)?
B. \( \frac{9}{4} \)
\( \sqrt{5}\approx2.236 \) और \( \frac{9}{4}=2.25 \), इसलिए \( \frac{9}{4} \) बड़ा है। बड़ी संख्या संख्या रेखा पर दाईं ओर होती है। / \( \sqrt{5}\approx2.236 \) and \( \frac{9}{4}=2.25 \), so \( \frac{9}{4} \) is greater. The greater number lies farther right.

If \( \sqrt{n} \) lies between (9) and (10) on the number line, which value of (n) is possible?
C. (91)
\(9<\sqrt{n}<10\) से (81<n<100), इसलिए (91) संभव है। धनात्मक सीमा को वर्ग करें। / From \(9<\sqrt{n}<10\), (81<n<100), so (91) is possible. Square the positive bounds.

Which value lies between \( \frac{4}{9} \) and \( \frac{5}{9} \) on the number line?
B. \( \frac{1}{2} \)
\( \frac{4}{9}\approx0.444 \), \( \frac{1}{2}=0.5 \), और \( \frac{5}{9}\approx0.556 \)। इसलिए \( \frac{1}{2} \) बीच में है। / \( \frac{4}{9}\approx0.444 \), \( \frac{1}{2}=0.5 \), and \( \frac{5}{9}\approx0.556 \). Hence \( \frac{1}{2} \) lies between them.

If \(p=-\sqrt{17}\) and (q=-4.2), which statement is correct on the number line?
A. (p>q)
\( -\sqrt{17}\approx-4.123 \), जो (-4.2) से बड़ा है। बड़ी संख्या दाईं ओर स्थित होती है। / \( -\sqrt{17}\approx-4.123 \), which is greater than (-4.2). The greater number lies to the right.
