Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Properties of Equality
The properties of equality state that if two expressions are equal, then they can be manipulated in the same way without changing their equality. This includes operations such as addition, subtraction, multiplication, and division. In the given statement, the manipulation of the fractions illustrates how these properties allow us to simplify or rearrange expressions while maintaining their equivalence.
