Draw the number line and represent the following rational numbers on it:

(i) $\frac{3}{4}$

(ii) $\frac{-5}{8}$

(iii) $\frac{-7}{4}$

(iv) $\frac{7}{8}$

(i) Since, $\frac{3}{4}$ lies between 0 and 1. To represent it on number line, divide this region into 4 equal parts and then mark the part with the value equal to 3.
