2.4 is a rational number because it can be expressed as an improper fraction in the form of 12/5
It is a rational number that is 2/9 as a fraction
88 = 88/1. The number can be expressed as a ratio of two integers and, therefore, it is a rational number.
2.600 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. Its equivalent, in rational form, is 2600/1000. You can simplify this rational fraction if required. However, the simplified form will not show that the number is accurate to three decimal places.
Certainly. Otherwise, there would be a rational number whose square was an irrational number; that is not possible. To show this, let p/q be any rational number, where p and q are integers. Then, the square of p/q is (p^2)/(q^2). Since p^2 and q^2 must both be integers, their quotient is, by definition, a rational number. Thus, the square of every rational number is itself rational.
3.8 is a rational number because it can be expressed as a fraction in the form of 19/5 in its simplest form.
2.4 is a rational number because it can be expressed as an improper fraction in the form of 12/5
2.4 is a rational number because it can be expressed as an improper fraction in the form of 12/5
18/10
5/10
2.4 expressed as an improper fraction is 12/5 thus proving that it is a rational number
24/10
If it can be expressed as a fraction then it is a rational number
There is no simple method. If you can write the number as a ratio of two integers, in the form p/q where q>0, then the number is rational. But it is often very difficult to show that such a representation is not possible.
It is a rational number that is 2/9 as a fraction
88 = 88/1. The number can be expressed as a ratio of two integers and, therefore, it is a rational number.
Integers are counting numbers or include them. 1/2 is a rational number that is not a couinting number.
