What is the distance of \(-\sqrt{0.81}\) from (0) on the number line?
B. (0.9)
\(\sqrt{0.81}=0.9\), इसलिए \(-\sqrt{0.81}\) की (0) से दूरी (0.9) है। दूरी परिमाण के बराबर होती है। / \(\sqrt{0.81}=0.9\), so the distance of \(-\sqrt{0.81}\) from (0) is (0.9). Distance equals magnitude.

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.
