To read a fraction in English you have to read the numerator and then the denominator with the ordinal. You can use plural if you have more than one part. For example, 1/3 is one third but 2/3 is two thirds. When the denominator is 2 you have to read “half”, 1/2 is one half, 5/2 is five halves. If the fractions is very big you can use “over”, 4/11 is four over eleven.
