Answer:
The statement "(a) all whole numbers are rational numbers" is true.
Explanation:
A rational number is the number which can be expressed in the from of
, where p, q are integers and q\\eq0.
(a.) As all the whole numbers (0,1,2,3...) can be expressed in the form of p/q having q=1.
Hence, the statement "(a) all whole numbers are rational numbers" is true.
(b). As the rational numbers can have the fractional value but any integers don't have fractional value, so all the rational numbers are not integers.
Hence, the statement "(b). All rational numbers are integers" is not true.
(c). As the rational numbers can have the fractional value but any whole numbers don't have fractional value, so all the rational numbers are not whole numbers.
Hence, the statement "(c). All rational numbers are whole numbers." is not true.
(d). Integers( ...,-2,-1,0,1,2,...) can be negative, but the whole numbers (0,1,2,...) can't be negative. So, all integers can't be whole numbers.
Hence, the statement "(d). All integers are whole numbers" is not true.
