Yes. Rational functions must contain rational expressions in order to be rational.
Yes. An equation has an "=" sign.
Rational numbers are closed under multiplication, because if you multiply any rational number you will get a pattern. Rational numbers also have a pattern or terminatge, which is good to keep in mind.
After multiplying or dividing two rational expressions it is sometimes possible to simplify the resulting expression.
A Rational number is a fraction of two integers; a rational expression is a fraction that contains at least one variable
true
Yes. Rational functions must contain rational expressions in order to be rational.
Suppose X1 = N1/D1 and X2 = N2/D2 are two rational expressions, where the numerators N1 and N2 and denominators D1 and D2 are simpler expressions. Then X1 * X2 = (N1*N2)/(D1*D2) and X1 / X2 = (N1*D2)/(D1*N2).
Yes, it applies to even multiplication of fractions and rational and irrational numbers.

Division by a non-zero rational number is equivalent to multiplication by its reciprocal.
