Ratio and Proportion Mystery

This resource written by Shirley Fall has eleven cards, each with a statement about how some students have performed in two papers of a mathematics test. Students are tasked to decide who should get the mathematics prize by working out their rank order. It is suggested that students draw up a table to show each student's marks and percentages on each paper and their average percentage over both papers. The mathematics students will need:

Fractions and percentages of quantities;

Equivalence of fractions and percentages;

Multiples of ratios;

Average of two percentages.
