Which of the following statements are true and which are false?
(i) \(\frac{-3}{5}\) lies to the left of 0 on the number line.
(ii) \(\frac{-12}{7}\) lies to the right of 0 on the number line.
(iii) The rational numbers \(\frac{1}{3}\) and \(\frac{-5}{2}\) are on opposite sides of 0 on the number line.
(iv) The rational number \(\frac{-18}{13}\) lies to the left of 0 on the number line
(i) True
\(\frac{-3}{5}\) is a negative number.
All negative numbers are less than 0 and therefore, lie to the left of 0 on the number line.
Hence,\(\frac{-3}{5}\) lies to the left of 0 on the number line.
(ii) False
\(\frac{-12}{7}\) is a negative number. All negative numbers are less than 0 and therefore, lie to the left of 0 on the number line.
Hence,\(\frac{-12}{7}\) lies to the left of 0 on the number line.
(iii) True
\(\frac{1}{3}\)is a positive number.
All positive numbers are greater than 0 and therefore, lie to the right of 0 on the number line.
Hence,\(\frac{1}{3}\) lies to the right of 0 on the number line.
\(\frac{-5}{12}\) is a negative number.
All negative numbers are less than 0 and therefore, lie to the left of 0 on the number line.
Hence,\(\frac{-5}{12}\) lies to the left of 0 on the number line.
Therefore, the rational numbers, \(\frac{1}{3}\)and \(\frac{-5}{12}\)are on opposite sides of 0 on the number line.
(iv) False
\( \frac{-18}{-13}=\frac{-18\times-1}{-13\times-1}=\frac{18}{13}\)
\(\frac{18}{13}\) is a positive number.
All positive numbers are greater than 0 and therefore, lie to the right of 0 on the number line.
Hence,\(\frac{18}{13}\) lies to the right of 0 on the number line.
