Examiners report
Very few candidates gained full marks in this question. A common error turned out to be that \(\frac{{22}}{7}\) and \(5 \times {10^{ - 2}}\) were not considered rational numbers. Also, \(0\) and \(\sin (60^\circ )\) were often placed incorrectly. However, it was encouraging that very few candidates placed values in more than one region.
