In a fraction, what is the term for the top number?

In a fraction, the top number is referred to as the numerator. The numerator indicates how many parts of the whole are being considered. For instance, in the fraction 3/4, the number 3 is the numerator, meaning that there are three parts being talked about out of four equal parts that make up the whole.

This terminology is essential because it helps in understanding the relationship between the numerator and the denominator; the denominator, which is the bottom number, tells how many equal parts make up the whole. In contrast, terms like divisor and dividend pertain to different mathematical operations, such as division. By distinguishing these terms, one can clearly convey mathematical concepts and solve related problems effectively.
