• can we do the same fraction in figure,example 1/2 we can do it in figure so why do we need number line
• Yes you can do it in any figure. However a number line is a more general way of doing it, it's just a straight line with some numbers plotted in! A figure is bigger and more complex and, as you know, there is an infinite number of different figures: I could represent fractions in a square, triangle, rectangle, circle, hexagon... you get the idea. Number lines are much more alike and pretty much the same, they just change on what numbers you want to plot.
