1. 3:1/4 = 3 × 4/1 = 12
2.2;1 1/2 = 2 : 3/2 = 2 × 2/3 = 4/3
3.5:1 3/7 = 5 : 10/7 = 5 × 7/10 = 7/2
4.6/7 : 4 = 6/7 × 1/4 = 6/28

1) 3 : ¼ = 3 × 4 = 12

2) 2 : 1 ½ = 2 : 3/2 = 2 × ⅔ = 6/3 = 2

3) 5 : 1 3/7 = 5 : 10/7 = 5 × 7/10 = 12/10 atau 1,2

4) 6/7 : 4 = 6/7 × ¼ = 6/28 = 3/14

5) 1 2/5 : 3 = 7/5 × ⅓ = 7/15

6) 3 4/9 : 6 = 31/9 × 1/6 = 31/54

7) 5/8 : ¾ = 5/8 × 4/3 = 20/24 = 5/6

8) 2 1/7 : 3/11 = 15/7 × 11/3 = 165/21 = 7 6/7

9) ½ : 1 4/9 = ½ : 13/9 = ½ × 9/13 = 9/26

10) 5/8 : 0,75 = 5/8 : ¾ = 5/8 × 4/3 = 20/24 = 5/6

11) 4 1/5 : 10,25 = 21/5 : 1025/100 = 21/5 × 100/1025 = 2100/5125 = 84/205

12) 7,25 : 0,5 = 725/100 : ½ = 725/100 × 2 = 1450/100 = 14 ½ atau 14,5

Semoga membantu :)
