If (A=-2.25) and (B=-0.75), what is the length of (AB) on the number line?
C. (1.5)
लंबाई (|-0.75-(-2.25)|=1.5) है। ऋणात्मक बिंदुओं के बीच भी दूरी धनात्मक होती है। / The length is (|-0.75-(-2.25)|=1.5). Distance between negative points is also positive.

Between which two integers will \(1-\sqrt{3}\) lie on the number line?
B. (-1) और (0)(-1) and (0)
\(\sqrt{3}\approx1.73\), इसलिए \(1-\sqrt{3}\approx-0.73\) है। यह (-1) और (0) के बीच है। / \(\sqrt{3}\approx1.73\), so \(1-\sqrt{3}\approx-0.73\). It lies between (-1) and (0).

Which relation between \(\sqrt{15}\) and (4) is correct on the number line?
A. \(\sqrt{15}<4\)
क्योंकि (15<16), इसलिए \(\sqrt{15}<4\) है। तुलना के लिए पूर्ण वर्ग से मिलाएं। / Since (15<16), \(\sqrt{15}<4\). Compare using the nearby perfect square.

If the distance from (2) to (5) is divided into (6) equal parts, what is the length of each part?
B. \(\frac{1}{2}\)
कुल दूरी (5-2=3) है और प्रत्येक भाग \(\frac{3}{6}=\frac{1}{2}\) होगा। पहले कुल दूरी निकालें। / The total distance is (5-2=3), and each part is \(\frac{3}{6}=\frac{1}{2}\). Find the total distance first.

In a similar segment, what is the fourth equal point from (2) when each part is \(\frac{1}{2}\)?
C. (4)
चौथा बिंदु \(2+4\times\frac{1}{2}=4\) है। बराबर भागों में आरंभिक बिंदु में कुल कदम जोड़ें। / The fourth point is \(2+4\times\frac{1}{2}=4\). Add the total step length to the starting point.

What is the best decimal estimate of \(\sqrt{\frac{1}{2}}\) on the number line?
B. (0.707)
\(\sqrt{\frac{1}{2}}\approx0.707\) होता है। अनुमान में वर्ग करके विकल्प जांच सकते हैं। / \(\sqrt{\frac{1}{2}}\approx0.707\). In estimation, you can square the options to check.

Which of these values will not lie between (0) and (1) on the number line?
C. (-0.1)
(-0.1) शून्य से छोटा है इसलिए (0) और (1) के बीच नहीं है। बीच की जांच में दोनों सीमाओं से तुलना करें। / (-0.1) is less than zero, so it is not between (0) and (1). Compare with both bounds when checking between values.

What is the distance between \(\frac{2}{5}\) and \(\frac{7}{10}\) on the number line?
C. \(\frac{3}{10}\)
\(\frac{2}{5}=\frac{4}{10}\), इसलिए दूरी \(\frac{7}{10}-\frac{4}{10}=\frac{3}{10}\) है। समान हर बनाकर घटाएं। / \(\frac{2}{5}=\frac{4}{10}\), so the distance is \(\frac{7}{10}-\frac{4}{10}=\frac{3}{10}\). Use a common denominator before subtracting.

If \(\sqrt{a}\) is exactly at (4.5) on the number line, what will be the value of (a)?
C. (20.25)
\(\sqrt{a}=4.5\) होने पर (a=(4.5)2=20.25) है। वर्गमूल हटाने के लिए वर्ग करें। / If \(\sqrt{a}=4.5\), then (a=(4.5)2=20.25). Square both sides to remove the square root.

If point (P) is \(\sqrt{0.04}\) unit to the right of (-0.4), what will be the value of (P)?
B. (-0.2)
\(\sqrt{0.04}=0.2\), इसलिए (P=-0.4+0.2=-0.2) है। दाईं ओर जाने पर जोड़ते हैं। / \(\sqrt{0.04}=0.2\), so (P=-0.4+0.2=-0.2). Moving right means addition.
