What does it mean for two expressions to be considered equivalent?
Understanding Equivalent Expressions
Equivalent expressions refer to mathematical expressions that have the same value, although they may look different. When two expressions are equivalent, it means they can be simplified to the same final expression. This can be achieved by combining like terms, applying the distributive property, or using other simplification rules.
To determine if two expressions are equivalent, you can evaluate both expressions with the same set of values for the variables. If both expressions yield the same result, they are considered equivalent. It is important to understand that equivalent expressions have the same value but may vary in their form due to different algebraic manipulations.
For example, in the context of fractions, equivalent fractions are fractions that represent the same value even though their numerators and denominators may be different. By multiplying or dividing both the numerator and denominator by the same number, you can create equivalent fractions. These fractions might look different, but they have the same overall value.
In summary, equivalent expressions are expressions that simplify to the same final form or value when evaluated with the same variables.
Equivalent fractions have the same value in their reduced form. Description Equivalent fractions can be written by multiplying or dividing the numerator and denominator by the same number. Two expressions are equivalent if they can be reduced to the same third expression, or if one expression can be written like the other.
