✏️ Part 2: Short Answers & Creative Task

5. You design a pattern with 3 red beads for every 7 yellow beads. If you want exactly 200 beads total, how many red and how many yellow beads will you use?

6. An artwork uses circles sized 2 cm : 5 cm. If each circle is scaled up by a factor of 3, what are the new sizes and does the ratio stay the same? Explain briefly.

7. In one sentence, explain how changing a ratio (for example from 1:3 to 3:1) affects the visual look of a repeating Aboriginal pattern.

8. Creative task: Draw a simple repeating motif that uses two colours with a ratio of 4:1 (four of Colour A for every one of Colour B). Label the counts and write the ratio. Then answer: if you repeat your motif so the total number of motifs is 100, how many of each colour will you need?
