Q3

1/7 =0.142857142857...=0.142857

and 2/7 = 0.28571428571428...=0.285714.

Here, the two decimal expansions are non-terminating recurring.

Hence, 1/7 and 2/7 are two rational numbers.

We know, between any two rational numbers, there are infinitely many irrational numbers.

An irrational number has non-terminating non-recurring decimal expansions.

Then an irrational number between 1/7 and 2/7 is

0.15015001500015....

Similarly, 0.21020020002... is another irrational number between 1/7 and 2/7

Q4

We can do it by using Pythagoras Theorem.

 

We can write 10 as follows:

10=9+1⇒10=32+12         

The construction steps are as follows:

1. Take a line segment AO=3 unit on the x-axis.   (consider 1 unit = 2 cm)   

2. Draw a perpendicular on O and draw a line OC=1 unit 

3. Now join AC with 10. 

4. Take A as center and AC as radius, draw an arc which cuts the x-axis at point E.

5. The line segment AC in the below diagram represents 10 units.
