Penjelasan dengan langkah-langkah:
1. 3/5 × 5/6 = 3×5/5×6= 15/30 -> 15/30 ÷ 3/3 (disederhanakan) = 5/10 ÷ 5/5 = 1/2
2. 7/10 × 2/5 = 7×2/10×5= 14/50 ÷ 2/2 = 7/25
3. 3/25 × 3/4 = 3×3/25×4 = 9/100
4. 4×3/5 = 4/1 × 3/5 = 4×3/5×1 = 12/5 = 2 2/5
5. 15 × 15/10 = 15× 3/2 = 45/2 = 22 1/2
6. 3/4 × 20 = 3/1 × 5 = 15
7. 1 1/5 × 14 = 6/5 × 14 = 84/5 = 16 4/5
8. 3× 2 1/3 = 3×7/3 =21/3 = 7
