Rationality of 4/15

Yes, four fifteenths (4/15) is a rational number. A rational number is any number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero. In this case, 4/15 can be expressed as the division of the numerator 4 by the denominator 15, both of which are integers.

Values of the Absolute Value (Modulus) Function

The absolute value or modulus function, denoted by |x|, returns the distance of a number from zero on the number line. It always returns a non-negative value.

- The modulus of a negative number is its positive counterpart. For example, the modulus of -5 is 5. - The modulus of a positive number is the number itself. For example, the modulus of 5 is 5. - The modulus of zero is also zero. The distance of zero from zero is zero.

Opposite Numbers: 2/5 and 5/2

No, two-fifths (2/5) and five seconds (5/2) are not opposite numbers. Opposite numbers have the same magnitude but opposite signs. In this case, 2/5 and 5/2 have different magnitudes and cannot be considered opposites of each other.
