Question

Represent $\frac{-13}{4}$ on a real number line.

Answer 1

$\frac{-13}{4}=-3\frac{1}{4}$
(i) Draw a line XY which extends endlessly in both the directions.
(ii) Take a point O on it and let it represent 0 (zero).
(iii) Taking the fixed length, called unit length, mark off OA = 1 unit and OB = 2 unit and OC = 3 unit on the left side of O.
(iv) Divide OA , AB, BC and CD into 4 equal parts. OP represents the rational number $\frac{-13}{4}$ of a unit.
