Sol:


To locate √4.7 on the number line, we have to follow the steps given below.

1) Mark the distance 4.7 from a fixed point A on a given line to obtain a point B such that AB = 4.7 units .

2)From B mark a distance of 1 unit and mark the new point as C.

3)Find the mid point of AC and mark that point as 'O'.Draw a semi circle with centre O and radius OC.

4)Draw a line perpendicular to AC passing through B and Intersecting the semi-circle at D.Then BD = √4.7.
