3/12 = 1/4 = 0.25, which terminates, so it is a rational number.
Integers are rational. Also, terminating decimal numbers, as well as repeating decimals (such as 3.12121212..., where "12" repeats over and over) are rational.

The number 12 is a natural number, a whole number, an integer, and a rational number. A natural number is a positive integer starting from 1, which includes 12. Whole numbers include all natural numbers along with zero, so 12 is also a whole number. Integers include all whole numbers along with their negatives, making 12 an integer. Lastly, a rational number is any number that can be expressed as a fraction, and 12 can be written as 12/1, making it a rational number.
6.5 is a rational number because it can be expressed as a fraction

It is a rational number
As,√144=√12×√12=12, which is an integer Therefore √144 is not irrational
It is a rational number. An irrational number is a decimal that is infinite and has no repition or pattern.
It is irrational.
-12 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
12 is the ratio of 12 and 1 ... nice and rational.
Integers are rational. Also, terminating decimal numbers, as well as repeating decimals (such as 3.12121212..., where "12" repeats over and over) are rational.
The square root of 144 is 12 which is a rational number
12 is the ratio of 12 and 1 ... nice and rational.
