Multiplying and Dividing Rational Expressions Peanuts Add x lb of peanuts. GET READY for the Lesson The Goodie Shoppe sells candy and nuts by the pound. One item is a mixture made with 8 pounds of peanuts and 5 pounds of cashews. Therefore, 8+ + 5 OF 13 of the mixture is peanuts. If the store manager adds an additional x pounds of peanuts to the mixture, then 8+x 13 + x of the mixture will be peanuts. 8 8 + 8 lb of peanuts 5 lb of cashews = 13 lb of nuts NUTS Simplify Rational Expressions A ratio of two polynomial expressions such as 8 + x is called a rational expression. Because variables in algebra often represent real numbers, operations with rational numbers and rational expressions are similar. To write a fraction in simplest form, you divide both the numerator and denominator by their greatest common factor (GCF). To simplify a rational expression, you use similar techniques.
