Explanation:
Integers are a subset of Rational Numbers because all Integers are Rational Numbers.
Explanation:
3 is integer but it can be written as \frac{3}{1} \ or \ \frac{6}{2},.. etc.
1
3
or
2
6
,..etc. which is rational form. Hence every integer can be express as Rational Number.
Thus the last option is correct.
Further, Integers can be defined as the whole numbers including zero and positive whole numbers. i.e. ......,-3, -2, -1, 0, 1, 2, 3,.....
Example: -546, 87855889, 0, etc.
Rational Number is the number in the form \frac{p}{q}
q
p
, where q≠0.
Example: \frac{2}{9}, \frac{-1}{267}, \frac{875}{2}, 3, etc.
