viii. 0,−34
The three numbers between 0 and −34 are −18,−28,−58

Intext Questions and Activities

Question 1.
Answer the following questions: (Textbook pg. no. 36)

1. Write all the natural numbers between 2 and 9.
2. Write all the integers between -4, and 5.
3. Which rational numbers are there between 12 and 34 ?

Solution:

1. 3, 4, 5, 6, 7, 8
2. -3, -2, -1, 0, 1, 2, 3, 4
3. 12=1×22×2=24=2×104×10=2040
   34=3×104×10=3040
   ∴ The rational numbers between 12 and 34 are 2140,2240,2540,2740 etc.
