These worksheets will teach your students to solve for variables that make a fraction undefined.

#### In this section we are trying to understand the fluid nature of algebraic functions. These are fractions that contain a variable either in the numerator or denominator of the fraction. When we use the term "undefined" we are describe a fraction that has no meaning. The way to give a fraction no meaning is to set the denominator to a zero value. In most cases, you will trying to figure out what you need to do mathematically to get the bottom to equal exactly zero. The set topics in this worksheet sled includes: identifying the values of specified variables that result in an undefined algebraic fraction (one whose denominator is equal to zero). The work involves simple balancing and comparison skills.

These worksheets will help you teach your students how to find the value of a variable that will make the fraction undefined for simply and more complex fractions.
