Q:

Every rational number is an integer.

A) TRUE B) FALSE
Answer & Explanation Answer: B) FALSE

Explanation:

Any integer 'i' can be written as i = i/1, which is a rational number. Clearly, 7/2,-5/4, etc... are rational numbers but they are not integers.


Hence, from the above analysis, every integer is a rational number but a rational number need not be an integer.


 


Therefore the given statement that 'Every rational number is an integer' is FALSE.
