12.52 is rational, as is any number that you can write out completely in decimal form.
200 is an integer and not a fraction. However, it can be expressed in rational form as 200/1.
Answer: 1 already is a rational number. If you want to get technical, you could write it as 1/1. Answer: Any integer is a rational number. No matter how you write it, it will still be a rational number. Answer: 10/10, 2/2, 3/3, 365/365, etc.
The simplest way is to write it as -0.2 which 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 rational equivalent is -2/10 which can be simplified, if required.
2.4 is a rational number because it can be expressed as an improper fraction in the form of 12/5

12.52 is rational, as is any number that you can write out completely in decimal form.
It is a rational number, in decimal form. In the form of a ratio, it is 11/100.
4.5 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 45/10. You can simplify this rational fraction if you require.
200 is an integer and not a fraction. However, it can be expressed in rational form as 200/1.
xxx is an integer and not a fraction. However, it can be expressed in rational form as 84/1.
Answer: 1 already is a rational number. If you want to get technical, you could write it as 1/1. Answer: Any integer is a rational number. No matter how you write it, it will still be a rational number. Answer: 10/10, 2/2, 3/3, 365/365, etc.
No. It is a rational number. Since it can be expressed in the form p/q = 2/1 where 2,1 are integers.
The simplest way is to write it as -0.2 which 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 rational equivalent is -2/10 which can be simplified, if required.
To write something in rational form means to write it as a fraction. If you are given a negative number in the form of a fraction, it is already in rational form. If you are given a decimal and wish to turn it into a fraction, just use 10, 100, etc as the denominator. In the case of a repeating decimal there is a method but that's another question!
