A number expressed as one integer written above another integer with a dividing line between them is known as what?

The term "fraction" refers to a mathematical expression that consists of two integers, where one integer, called the numerator, is placed above another integer, called the denominator, with a dividing line between them. This format represents a part of a whole, indicating how many parts of a certain size are considered. For example, in the fraction 3/4, 3 is the numerator, representing the number of parts taken, while 4 is the denominator, indicating the total number of equal parts that make up a whole.

In contrast, a decimal represents a fraction expressed in a different form, typically involving a base of ten, without the dividing line seen in fractions. An integer is a whole number that can be positive, negative, or zero but does not include fractions or decimals. A whole number is a non-negative integer, which excludes fractional or decimal representations. Thus, identifying the correct term for an expression containing a numerator and denominator clearly aligns with the definition of a fraction.
