Q. 22 Find five rational numbers between 2/3 and 4/5 (4
​

Answer 1

Answer:

2/3 = 10/15= 40/60

4/5 = 12/15= 48/60

So 5 rational numbers can be

41/60, 42/60, 43/60, 44/60, 45/60 etc

Explanation:

2/3 = 2 x 5 / 3  x 5  

      = 10 / 15  

4/5 = 4 x 3 / 5 x 3  

      12 / 15  

we can find 5 rational numbers betwen 2/3 and 4/5 by multiplying them with 5 + 1 = 6  

10 / 15  X 6 /6  

= 60 / 90  

12/ 15 X 6 /6  

= 72 / 90  

the rational numbers = 61 / 90  62 /90  63 /90  64/90  65/90  66/90   67 /90

Answer 2

Answer:

2/3×5=10/15×5=50/75

4/5×3=12/15×5=60/75

So between 50/75 and 60/75

51/75, 52/75, 53/75, 54/75, 55/75
