# Is Every Rational Number an Integer?

Is every rational number an integer?

Every integer is a rational number but a rational number need not be an integer.

We know that 1 = 1/1, 2 = 2/1, 3 = 3/1, 4 = 4/1 and so on ……. .

also, -1 = -1/1, -2 = -2/1, -3 = -3/1, -4 = -4/1 and so on …….. .

In other words, any integer a can be written as a = a/1, which is a rational number.

Thus, every integer is a rational number.

Clearly, 3/2,-5/3, etc. are rational numbers but they are not integers.

Hence, every integer is a rational number but a rational number need not be an integer.

Let us determine whether the following rational numbers are integers or not:

(i) 2/5

2/5 is not an integer. Since we cannot express 2/5 without a fractional or decimal component

(ii) 8/4

8/4 is an integer. Since if we simplify 8/4 to its lowest term we get 2/1 = 2, which is an integer.

(iii) -5/-5

-5/-5 is an integer. Since if we simplify -5/-5 to its lowest term we get 1/1 = 1, which is an integer.

(iv) -15/2

-15/2 is not an integer. Since we cannot express -15/2 without a fractional or decimal component

(v) -32/8

-32/8 is an integer. Since if we simplify -32/8 to its lowest term we get -4, which is an integer.

(vi) 49/-9

49/-9 is not an integer. Since we cannot express 49/-9 without a fractional or decimal component

(vii) -75/-20

-75/-20 is not an integer. Since if we simplify -75/-20 to its lowest term we get 15/4 and we cannot express 15/4 without a fractional or decimal component

(viii) 500/-10

500/-10 is an integer. Since if we simplify 500/-10 to its lowest term we get 50/-1 = -50, which is an integer.

So, from the above explanation we conclude that every rational number is not an integer.
