It's called a vinculum.
It is the solidus line that separates the numerator from the denominator in a fraction
A vulgar fraction is a common fraction which is written as one integer (whole) number over another integer with a line between the two, for example 3/4.The line separating the two numbers can be sloping (as above) or horizontal, as in:3-4but this latter form is not always easy to display and use on a computer (especially here).
The line that separates the numerator and denominator in a fraction is called the "fraction bar" or "vinculum." It indicates division, showing that the numerator is to be divided by the denominator. This visual representation helps clarify the relationship between the two numbers.
The solidus
The top line of a fraction is called the "numerator". This serves to "numerate" the number of objects that you are finding a fraction of. For example, in the fraction 3/4, you are finding three quarters of something else.
They are called these names: 1. solidus 2. fraction bar 3. division bar
A fraction has two parts. On the top is the numerator, and on the bottom is the denominator. The line separating them is called the vinculum.
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.

It is usually called the division bar or the fraction bar
The number above the line in a fraction is called the numerator. The number below the line is called the denominator. So in the fraction 5/7 5 is the numerator and 7 is the denominator.
