Expressions have to contain numbers and letters.
They are expressions.
All expressions DO contain equals signs.
a rational function.
an algebraic expression
Yes, equations contain expressions. An equation is a mathematical statement that asserts the equality of two expressions, typically separated by an equals sign. For example, in the equation (2x + 3 = 7), both (2x + 3) and (7) are expressions. Thus, equations serve to relate different expressions to one another.

In the same way that you would factorise any other expressions that do not contain an equality sign depending on the expressions of which none have been given.
numerical expression
yes.
They do not contain an equality symbol.
Yes. Rational functions must contain rational expressions in order to be rational.
Equation
Algebraic expressions can be simplified by combining together like terms but there are no solution because they don't contain equality signs
