Represent these numbers on the number line.

- 7/4
- -5/6

Write five rational numbers which are smaller than 2.

2 can be written as 14/7

So the five rational number smaller than

8/7, 9/7,10/7,11/7,12/7

Find ten rational numbers between (-2/5) and 1/2

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

Find five rational numbers between

(i) 2/3 and 4/5

(ii) -3/2 and 5/3

(iii) ¼ and 1/2

- 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

- 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

¼ = 8/32

½= 16/32

So five rational number will be

10/32, 11/32,12/32,13/32,14/32

Write five rational numbers greater than - 2.

-2 can be written as -14/7

So the five rational number smaller than

-8/7,-9/7,-10/7,-11/7,-12/7

Find ten rational numbers between 3/5 and 3/4

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
