Which inequality represents the variable \(u\) being less than or equal to 25?

Answer and explanation

Correct answer: \(u\le 25\)

‘Less than or equal to 25’ means that \(u\) may be smaller than 25 or exactly equal to 25. This is represented by \(\le\), so \(u\le 25\) is correct. Option A excludes the case \(u=25\). Exam tip: when ‘or equal to’ is stated, choose the inequality symbol that includes the equality bar.
