Q.4. Represent 9.3 on the number line.

Solution:

  1. Draw a line segment of unit 9.3. Extend it to C so that BC = 1 unit.

  2. Now, AC = 10.3 units. Find the midpoint of AC. Let it be O.

  3. Draw a semi circle with radius OA = OC and centre O.

  4. Draw a perpendicular to AC at point B which intersects the semicircle at D. Join OD.

  5. Now, OBD is a right angled triangle. The length of BD is 9.3.

  6. Taking BD as radius and B as centre draw an arc which cuts the line segment AC at E. Now BE is equal to 9.3.
