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

(1) Draw a line AB = 9.3 units and BC = 1 unit.

(2) Find the mid-point of AC and mark it as O. Taking O as the centre and OA as the radius, draw a semi-circle.

(3) From B, draw a perpendicular to AC. Let it meet the semi-circle at D. Taking B as the centre and BD as the radius, draw an arc that intersects the line at E.

Now, the distance BE on the line is units.
