notes

To represent rational number on a number line. Let us see 

The point on the first number line which is half way between 0 and 1 has been labelled `1/2` .
 Also, the first of the equally spaced points that divides the distance between 0 and 1 into three equal parts can be labelled `1/3` , as on second  number line .
The point to be labelled is twice as far from and to the right of 0 as the point  labelled `1/3`. So it is two times `1/3` , i.e. `2/3` .You can continue to label equally-spaced points on the number line in the same way. In this continuation, the next marking is 1. You can  see that 1 is the same as `3/3` .
