Question 1.
Solution:
We know that a fraction $$\frac { p }{ q }$$ is terminating if prime factors of q are 2 and 5 only.
Hence.
(i) $$\frac { 13 }{ 80 }$$ and $$\frac { 16 }{ 125 }$$ are the terminating decimals.

Question 2.
Solution:     Question 3.
Solution:
(i) Let,x = 0.$$\overline { 3 }$$ = 0.3333…(i)
Then, 10x = 3.3333….       Question 4.
Solution:
(i) True, because set of natural numbers is a subset of whole number.
(ii) False, because the number 0 does not belong to the set of natural numbers.
(iii) True, because a set of integers is a subset of a rational numbers.
(iv) False, because the set of rational numbers is not a subset of whole numbers.
(v) True, because rational number can be expressed as terminating or repeating decimals.
(vi) True, because every rational number can be express as repeating decimals.
(vii) True, because 0 = $$\frac { 0 }{ 1 }$$, which is a rational number Ans.
