The decimal representation of a rational number is
- either terminating or repeating
- always terminating
- always non-terminating
- either terminating or non-repeating
The decimal representation of an irrational number is
- always non-terminating
- neither terminating nor repeating
- always terminating
- either terminating or non-repeating
Q4) Between any two rational numbers there
- is no irrational number
- are exactly two rational numbers
- is no rational number
- are many rational numbers
Q5) The product of two irrational numbers is
- always an integer
- always irrational
- always rational
- either irrational or rational
Explanation
The decimal representation of a rational number is
either terminating or repeating
- always terminating
- always non-terminating
- either terminating or non-repeating
Ans The answer is none of the above
When rational numbers are converted into decimal fractions they can be both terminating and non-terminating decimals.
Q4) Between any two rational numbers there
- is no irrational number
- are exactly two rational numbers
- is no rational number
- are many rational numbers
Ans Between any two rational numbers there are many rational numbers
To find a rational number between p and q, we can add
r and s and divide the sum by 2, that is p+q/2 lies between p and q.
As an example,
5
/2 is a number between 2 and 3.
The product of two irrational numbers is
- always an integer
- always irrational
- always rational
- either irrational or ration
Ans The product of two irrational numbers is either irrational or rational
