2*2 = 4/1 and .4 = 4/10 are possible solutions.
Any number that can be expressed as a fraction is a rational number otherwise it is an irrational number.
I can see no rational expression below.
A polynomial expression is considered a rational expression when it is expressed as a fraction where both the numerator and the denominator are polynomials. For example, the expression ( \frac{x^2 + 3x + 2}{x - 1} ) is a rational expression because its numerator ( x^2 + 3x + 2 ) and denominator ( x - 1 ) are both polynomials. Rational expressions can be simplified, added, or multiplied, just like rational numbers, provided that the denominator is not zero.
To determine what expression is rational to 01.05 MC, we need to understand that rational expressions consist of a ratio of two polynomials. For example, a rational expression could be ( \frac{2x + 3}{x - 1} ) or ( \frac{x^2 - 4}{x + 2} ). Specifically, if "01.05 MC" refers to a specific quantity in a context, we would need more details about that context to provide a precise rational expression.

An expression produces a rational number when its value can be expressed as a fraction ( \frac{a}{b} ), where ( a ) and ( b ) are integers and ( b \neq 0 ). For example, the expression ( 3 + 2 ) evaluates to ( 5 ), which is rational, as it can be represented as ( \frac{5}{1} ). Similarly, any expression involving addition, subtraction, multiplication, or division of rational numbers (as long as division by zero is avoided) will yield a rational result.
A rational function is defined as a function that can be expressed as the quotient of two polynomials. However, it can also be represented in forms that do not explicitly show a rational expression, such as a polynomial or a constant function, which can be thought of as a rational function with a denominator of 1. For example, the function ( f(x) = 3x^2 + 2 ) is a polynomial and can be considered a rational function because it can be rewritten as ( f(x) = \frac{3x^2 + 2}{1} ). Thus, while the standard form includes a rational expression, the definition encompasses more than just explicit fractions.
