**drwls**, Sunday, January 25, 2009 at 9:37amWhen adding fractions like 1/3 and 3/5, the Lowest Common Denominator is the smallest number that is a integer-multiple of both 3 and 5. In this case it would be 15. You would get the sum by adding 5/15 and 9/15 to get 14/15.

The simplest from of a fraction is the form in which any integer numbers that are factors of both numerator and denominator are cancelled out. For example, for 12/15, the simplest form would be

(4*3)/(5*3) = 4/5

The reciprocal of any fraction that has the form a/b is b/a. Just turn it upside down. The reciprocal of 5/7 is 7/5, for example. The reciprocal of an integer a is 1/a.
