(1) We see that 3.45, is located between 3 and 4. To get a more accurate visualization
of the representation, we divide this portion of the number line into 10 equal parts.
(ii) Now, we see that 3.45, lies between 3.4 and 3.5. To visualize 3.45 accurately,
we again divide the portion between 3.4 and 3.5 into ten equal parts.
(ii) Now to visualize 3.45 more accurately, we again divide the portion between 3.45
and 3.46 into ten equal parts and use a magnifying glass to visualize that
between 3.455 and 3.456.

Answer 1

Answer:

Then from mid point,make a semi circle from point A to point B.

Then make a 90°angle at point B.

From point B.. The intersecting line where the 90° and the semi circle line intersects,make an arc. to the right side.

Then you can mark the No. line from point B as 0 then as the no. line goes.

Thanks!
