hey mate...
here is your answer...
22. (i)refer the attachment.
(ii)
23. 3 = 3/1
4 = 4/1
if u want 6 rational numbers in between, u have to multiply both of them ( numerator and denominator) with 7, so you can get 6 in between.
after multiplying you get,
3/1 x 7/7 = 21/7
and
4/1 x 7/7 = 28/7
u have now got the denominators equal and now can mention the six rational numbers you have got between them i.e.
22/7, 23/7, 24/7, 25/7, 26/7, 27/7.
so now you have got six rational numbers between 3 and 4.

24. x= 1.272727.............
100x=127.272727................
100x=127.272727............
x=. 1.272727
99x=126
x=126/99
x= 14/11
.................................................................................................
25. Given:
0.9 = 0.99999…
Let x = 0.99999……. (1)
Here only one digit is repeating so multiply by 10 on both sides
10 × x = 10× 0.99999….
10x = 9.9999…. (2)
On subtracting equation 1 from equation 2
10x- x = 9.9999…. - 0.9999….
9x = 9
x = 9/ 9 = 1
Here , 0.9 = 1
Yes we are surprised to get an integer 1, because 0.9999…. goes on forever so there is no gap between 1 and 0.999 9... and hence they are equal.
