Practice Equivalence in Math
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
When two expressions, numbers, or objects represent the same value or are interchangeable in every relevant context.
\frac{1}{2}, 0.5, and 50\% are equivalent—different forms, same value.
Example 1
easyAre \(3 \times 4\) and \(6 \times 2\) equivalent? Show your work.
Example 2
mediumFind a value of \(n\) that makes \(4 \times n = 2 \times 10\) true. Explain what equivalence means here.
Example 3
easyIs \(15 + 7\) equivalent to \(11 + 11\)? Show your work.
Example 4
mediumFind \(n\) such that \(5 \times 8 = n + 20\).
