Here are the solutions to the questions. Q1. Calculate these products quickly without using direct multiplication. a) 25 × 12 Step 1: Break down 12 into 4 × 3. 25 × 12 = 25 × (4 × 3) Step 2: Group 25 × 4 to get 100. = (25 × 4) × 3 = 100 × 3 = 300 b) 25 × 240 Step 1: Break down 240 into 24 × 10, then 4 × 6 × 10. 25 × 240 = 25 × (4 × 6 × 10) Step 2: Group 25 × 4 to get 100. = (25 × 4) × 6 × 10 = 100 × 6 × 10 = 600 × 10 = 6000 c) 250 × 120 Step 1: Break down 250 into 25 × 10 and 120 into 12 × 10. 250 × 120 = (25 × 10) × (12 × 10) Step 2: Rearrange and use the result from Q1a (25 × 12 = 300). = (25 × 12) × (10 × 10) = 300 × 100 = 30000 *d) $2500 ×
