But you do need it for addition or sutraction.no you do not. You don't need one in division either. A common denom is only used in addition and subtraction.a equation for multiplying would beA a A*a-- * -- = -----B b B*bDividing is similar, just multiply by the inverse.A a A*b-- / -- = -----B b B*aAdding and subtracting are a little more complicated. Here is a formula to make finding the common denominator easy.A a (A*b)+(a*B)-- + -- = ---------------B b B*bA a (A*b)-(a*B)-- - -- = ---------------B b B*b
