The line between the numerator and the denominator of a fraction is the the solidus line
This is the denominator, which is the bottom line of the fraction.
It's sometimes known as the 'divison bar' or 'fraction bar'.
It is the solidus line that separates the numerator from the denominator in a fraction.
The name of a fraction with a larger number on top is called an improper fraction.
The line separating the numerator and denominator when displayed as one number over another is called Vinculum, or sometimes referred to as the fraction bar. If the line is a slanting line (such as in "9/10"), it's referred to as the solidus.
The top number is called the numerator and the bottom number called the denominator. The line that usually separates the numerator and denominator. If slanting it is called a solidus or forward slash, for example 3⁄4. If the line is horizontal, it is called a vinculum or, informally, a "fraction bar"
i think that if you have an address like 123 1st street youdon't add a line between the house number and street number. my coworker says that is professional to add a line between the house number and the name of the street with a number name.
