A fraction (from Latin fractus, broken) represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters.
The present value factor is usually found on a table that lists the factors based on the term (n) and the rate (r). Once the present value factor is found based on the term and rate, it can be multiplied by the dollar amount to find the present value. Using the formula on the prior example, the present value factor of 3 years and 10% is .751, so $500 times .751 equals $375.66.
