5/8 is already in fraction form. A fraction consists of two numbers: the numerator (top number) and the denominator (bottom number). In this case, 5 is the numerator, and 8 is the denominator. This fraction represents the division of 5 by 8, which can also be interpreted as a part of a whole. To visualize it, if you divide something into 8 equal parts, taking 5 of those parts would mean you have 5/8 of the whole.
