The answer is given below.
-3 is a rational number
The math definition of a rational number is any number a/b so that both a and b are integers, except b ( the denominator) cannot be zero. So if you can manipulate the expressions to become this form, a/b, then it is the equavilent of a rational expression. Rational algebraic expressions are similar, except they contain variables. The same condition for the denominator must be true. The entire expression in the denominator cannot equal zero, but the variable might equal zero. Ex. a 1 / (x-1) .... x-1 cannot equal zero, which means that x cannot equal 1. Ex. b (1/3)/(1/4) can be simplified into 4/3 which is a rational number.
Yes. It can be written as -3/1.
All integers are rational numbers, not all rational numbers are integers. Rational numbers can be expressed as fractions, p/q, where q is not equal to zero. For integers the denominator is 1. 5 is an integer, 2/3 is a fraction, both are rational.
Because it can be expressed as an improper fraction in the form of -3/1 and so therefore it is a rational number
I can see no rational expression below.
When x = -3
This is wrong
4
Negative 12 minus 3 plus 9 is equal to -6
-3 is a rational number
Any integer, whether it is positive or negative, is a rational number.
-2/3 is a rational number

Yes: -12/-3 = 4
Yes. It can be written as -3/1.
The answer would normally depend on the form of the expression: (-10)^3 or -10^3 but in this case they both equal -1000
