• Multiplying rationals means: a/b * c/d = ac/bd and reduce if possible.
• Multiplying rationals means: a/b * c/d = ac/bd and reduce if possible.
• Dividing rationals means: a/b / c/d = a/b * d/c = ad/bc and reduce if possible.
• Dividing rationals means: a/b / c/d = a/b * d/c = ad/bc and reduce if possible.
• Remember that when factoring a polynomial, the factored value must be removed from every term in the expression, not just the first term.
