Yes, because 13 is just that- it doesn't continue on forever, like an irrational number, but is simply ten and three, 13. Also, as a rational number, it can be written as a fraction: 13 over 1.
However, 13 is prime, meaning that it can only be multiplied by 1 and itself. Because of this, if you asked for the square root of 13, you would get an irrational number.
Yes 13/19 is rational because any number that can be expressed as a fraction is a rational number
-13 is rational and an integer.
Yes
6.5 is a rational number because it can be expressed as a fraction
0.13131313 is a rational number, as it's a recurring number, and all recurring numbers are rational. To prove this, you first multiply by 10 until the decimal part of the number is the same. In this case, 0.13131313...x100=13.13131313.... Then you take off the original number 0.131313...x100 - 0.131313... = 13 Now you can simplify the left hand side 0.131313...x99=13 And divide both sides by 99, to get 0.131313....=13/99 So the original number can be expressed as 13/99, proving it's rational.
-13 is a rational number
13 is the ratio of 13 to 1 ... nice and rational.
13 is rational
-13/12 is a rational number
Yes 13/19 is rational because any number that can be expressed as a fraction is a rational number
13 is the ratio of 13 to 1, so it's rational.
It is a rational number
-13 is rational and an integer.
The square root of 169 is 13 which is a rational and also a Prime number
13 is an integer. All integers are rational.
If you mean 213 then it is a rational number because all integers or whole numbers are rational numbers.
Yes
