It is a rational number, in decimal form. In the form of a ratio, it is 11/100.
12.52 is rational, as is any number that you can write out completely in decimal form.
- 2 (A+)
Not completely to its end. If you can completely write a number with digits, then it's a rational number.
It is still a rational number.
It is a negative rational number in decimal form. It is also a real number.
0.7 IS is a rational number. It is in the form of a terminating decimal.
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!
I think it's a repeating decimal.
