The horizontal bar in a fraction is called a vinculum or, informally, a "fraction bar".
A synonym for fraction bar is "vinculum." This term refers to the horizontal line that separates the numerator and denominator in a fraction. In some contexts, it may also be called a "division line" or "fraction line."
fraction bar
The fraction form is just that - 4/7. You would usually use a horizontal bar to separate the 4 and the 7.
Now why do you suppose we say "over" in that description ? Could it be because the fraction has the '5' written 'over' the '12', with a horizontal bar between them ?
vinculum
There is no vertical bar in a fraction. A fraction is written with either a horizontal bar or a slanted bar, which is technically called a "vinculum", but most people call it a "fraction bar".
In any proper or improper fraction such as 3/4, the fraction bar, when shown as being horizontal, is called the vinculum. When shown as being slanted, it is called a solidus.

If you are talking about the fraction bar in mathematics, the "fraction bar" is the real name. It is sometimes called a vinculum (although this is a misuse of the word). The fraction bar in amateur radio, also known as the forward slash is officially known as the "fraction bar."

The number below the bar is called the denominator.The top number of the fraction tells us how many parts we have.We call it the numerator.The bottom number tells us how many parts are in the whole.We call it the denominator.
