Question 2
a) The part-part ratios are 3 : 4 (squares to circles), 3 : 2 (squares to arcs), 4 : 2 (circles to arcs)
Note: 4 : 3, 2 : 3, and 2 : 4 are not different part-part ratios, just flips of existing ones.
b) The part-whole ratios are 3 : 9 (squares to all), 4 : 9 (circles to all), 2 : 9 (arcs to all)
