pdf Substitution Practice - Working With Fractions

This worksheet gives students targeted practice with evaluating algebraic expressions through substitution when the variable represents a fraction. Students replace the variable with a given fractional value and then simplify the resulting expression, reinforcing accuracy with fraction multiplication and division in an algebraic context. The expressions include both products and quotients, requiring careful attention to fraction operations and order of operations.

Problems are organized into sets, each with a different assigned value of the variable, allowing students to focus on one substitution value at a time. For example, students evaluate expressions such as \(\tfrac{5}{2}x\) or \(7 \div x\) when a value like \(x = \tfrac{2}{3}\) is given. This structure helps students clearly separate the substitution step from the computation step while building fluency with rational numbers in algebra.
