Yes, all fractions are real numbers. A fraction is defined as the ratio of two integers, where the numerator is the integer above the line, and the denominator is the integer below the line. For example, in the fraction 3/4, 3 is the numerator and 4 is the denominator.
The set of real numbers includes all the rational numbers, which are numbers that can be expressed as a fraction, as well as all the irrational numbers, which cannot be expressed as a simple fraction. Since fractions can be expressed in decimal form (such as 0.75 for 3/4), they fall within the category of rational numbers and thus are part of the real number system.
In summary, every fraction represents a specific real number, making them inherently part of the broader set of real numbers.
