In order to represent
74 on the number line, we first draw a number line and mark a point O on it which represent 'O' as shown in the figure.
Now we have to find a point, say, N on the number line which represents the numerator 7 of the rational number
74
So, N is the point that represents the integer 7 on the number line and is on the right hand side of the point O. Divide the segment ON into four (Denominator of
74) equal parts (with the help of a ruler). Let A, B, C, be the points of division as shown in the figure.
Then OA = AB = BC = CN.
By construction, each segment OA, AB, BC and CN represents
14th of segment ON. Therefore, the point A represents the rational number
74.
