Question 1  
Represent these numbers on the number line.
  1. 7/4
  2. -5/6

Answer

Question  2  Represent on the number line.


Answer:

Question 3
Write five rational numbers which are smaller than 2.
Answer:
2 can be written as 14/7
So the five rational number smaller than
8/7, 9/7,10/7,11/7,12/7
Question 4
Find ten rational numbers between (-2/5) and 1/2
Answer:
Creating same denominator of both the numbers
-2/5   = -8/20
1/2= 10/20
So ten rational numbers will be
-7/20,-6/20,-5/20,-4/20,-3/20,-2/20,-1/20, 0 ,1/20,2/20
Question 5  
Find five rational numbers between
(i) 2/3 and 4/5
(ii) -3/2   and 5/3
(iii) ¼ and 1/2
Answer:
  1. Creating same denominator 2/3   = 30/45
    4/5= 36/45
    So five rational number will be
    31/45, 32/45, 33/46, 34/45,35/45
  2. Creating same denominator -3/2   =  --9/6
    5/3= 10/6
    So five rational number will be
    -8/6,-7/6,-1,-5/6,-4/6
Creating same denominator
¼   = 8/32
½= 16/32
So five rational number will be
10/32, 11/32,12/32,13/32,14/32
Question 6
Write five rational numbers greater than - 2.
Answer:
-2 can be written as -14/7
So the five rational number smaller than
-8/7,-9/7,-10/7,-11/7,-12/7
Question 7
Find ten rational numbers between 3/5 and 3/4
Answer:
3/5= 48/80
¾=60/80
So ten rational numbers are
49/80, 50/80, 51/80, 52/80, 53/80, 54/80, 55/80, 56/80, 57/80, 58/80
