tolong jawab no 12 sampai 15 dengan caranya ya guys

12. 0,48 : 12%

= 48/100 : 12/100

= 12/25 × 100/12

= 4


13. 2,56 : 160%

= 2 56/100 : 160/100

= 2 28/50 × 100/160

= 2 14/25 × 100/160

= 64/25 × 100/160

= 8/5

= 1 3/5

= 1,6


14. 1/2 : 0,6 : 25%

= 1/2 : 6/10 : 25/100

= 1/2 × 10/6 × 100/25

= 5/6 × 100/25

= 50/15

= 10/3

= 3 1/3

= 3,333 (tak terhingga)


15. 0,8 : 3/4 : 60%

= 8/10 × 4/3 : 60/100

= 16/15 : 3/5

= 16/15 × 5/3

= 16/9

= 1 7/9



maaf kalo salah..........semoga membantu...........
