Answer 1

1) 32×5 = (16×2)× 5= (2×5) ×16= 160

2) 82×5 = (41×2) ×5 = (2×5) × 41= 410

3) 24×5 = (12×2) ×5= (2×5) ×12= 120

4) 16×25 = (8×2) ×25 = (25×8) ×2 = 400

5) 28×25 = (14×2) × 25 = (25×2) ×14 = 700

6) 44×25 = (22×2) × 25 = (25×2) × 22 = 1100

7) 125×16 = (8×2) × 125 = (125×8) ×2 =2000

8) 125×88 = (44×2) × 125 =

(125×2) ×44=11000

9) 72×125 = (36×2) ×125 = (125×2) × 36 = 9000
