If (a=\sqrt{17}), (b=\frac{33}{8}), and (c=4.13), which number will be farthest to the right on the number line?
Answer and explanation
Correct answer: \(c\)
On converting the values to decimals, \(\sqrt{17}\approx 4.1231\), \(\frac{33}{8}=4.125\), and \(c=4.13\). Thus, \(4.13>4.125>4.1231\), so \(c\) is farthest to the right on the number line. The closest distractor is \(b\), but \(4.13\) is greater than \(4.125\). Exam tip: Convert irrational and fractional values to comparable decimal forms before ordering them.
