tolong dengan caranya

Answer 1

1. 1/2 * 1/3 = 1/6

2. 3/4 * 1/2 * 2/5 = 6/40 = 3/20

3. 4/5 = 0,8 ; 40% = 40/100 = 0,4
0,8 * 2,5 * 0,4 = 0,08

4. 1/4 * 1 1/3 = 1/4 * 4/3 = 1/3

5. 2 2/3 * 1 3/5 = 8/3 * 8/5 = 64/15 

6. 2 2/5 * 3 1/4 * 1 1/2 = 12/5 * 13/4 * 3/2 = 468/40 = 117/10

7. 5* 2/5 = 2

8. 1/2 : 1/5 = 1/2 * 5/1 = 5/2

9. 3/4 : 4 = 3/4 : 4/1 = 3/4 * 1/4 = 3/16

10. 3 3/4 : 1 1/2 : 1/4 = 15/3 : 3/2 : 1/4 = 15/3 * 2/3 * 4/1 = 120/9 = 40/3 = 13 1/3
