Answer 2

1) 1/3 : 1/9 = 1/3 × 9/1 = 9/3 = 3×3/3 = 3

2) 3/8 : 1/2 = 3/8 × 2/1 = 3×2/8 = 3×2/4×2 = 3/4 = 0,75

3) 4/9 : 8/9 = 4/9 × 9/8 = 4/8 = 4/4×2 = 1/2 = 0,5

4) 1/12 ÷ 1/6 = 1/12 × 6/1 = 6/12 = 6/2×12 = 1/2 = 0,5

5) 3/5 : 1/25 = 3/5 × 25/1 = 3×25/5 = 3×5×5/5 = 3×5 = 15

6) 2/7 : 3/7 = 2/7 × 7/3 = 2×7/3×7 = 2/3

7) 1/10 : 1/10 = 1/10 × 10/1 = 10/10 = 1

8) 3/4 : 5/8 = 3/4 × 8/5 = 3×8/5×4 = 3×2×4/5×4 = 3×2/5 = 6/5 = 1 ×1/5 = 1,2
