Simple Fraction Slash
The simple fraction is a fraction in which the numerator and denominator consist of numbers that only contain numbers, decimals, commas, or spaces, and in which the fraction line is drawn between two numbers placed in a vertical or semi-vertical position.
The number sign is used for the numerator that comes before the simple fraction line and the denominator that comes after it. The simple fraction line resumes the number mode, so the sign of the number is not written before the number that represents the denominator in the simple fraction. A simple numeric fraction line – or what is known as a fraction slash – in braille consists of a single cell with the dots 34.
Important note: The dots representing the fraction sign are the same as the dots representing the letter ”alef” with “hamza above “أ”. This sign can only be entered using the Arabic table after a number. But if you want to write the letter ”alef” with “hamza” over it immediately after a number, then you must write it preceded by the letter sign, with the dots 56.

The Italic Slash
If two numbers are on the same line in the regular script with a slash between them, as in 20/20, then this is not considered a fraction, although some use it instead of the fraction sign because it is easy to type from the keyboard. So, this expression is typed in braille as it is in a regular font using forward italic slash.
The braille italic slash consists of two cells, starting with the dots 456 followed by the dots 36. Please note that the forward slash ends the numbers mode, so you must write the number sign after the number that follows it.
When the numerator or denominator is not completely numeric, such as containing letters and numbers, then the signs of the general fraction must be used. In this case, the numerator and denominator are written between two signs, namely the general open fraction parenthesis and general close fraction parenthesis, and the general fraction dash is used.
The general open fraction sign consists of two cells with the dots 12356-4, and the general close fraction sign consists of two cells with the dots 23456-4.
The general fraction slash consists of two cells with the dots 456 in the first cell and the dots 34 in the second cell, and this sign ends the number mode, so the next number must be written preceded by the number sign.
Important note: These three signs cannot be used in the Arabic braille module 2 table due to their contradiction with abbreviations. If you are dealing with general fractions, you should use the verbatim Arabic Braille table.
Note: General fraction slashes were used in this example because the numerator here contains something other than numbers, which is the plus sign.
