Creative task - students create their own problems

Explanation

(i) 60% = 2×302 \times 30% = 140, 90% = 3×303 \times 30% = 210, 120% = 4×304 \times 30% = 280 (ii) 10% = 215/10 = 21.5, 1% = 2.15, 6% = 6×2.156 \times 2.15 = 12.9 (iii) If 90% = 270, then n = 300. 9% = 27, 18% = 54, 100% = 300 (iv) This is a creative extension activity for students to design similar problems.
