Jawab no 9,11,12,13,14,15 pakai Cara Yamaha

9. 46/68 : 2/2 = 23/24

11. 60/100 x 5/10 : 4/5 = 60/100 x 5/10 x 5/4 = 30/80 = 3/8

12. 3 3/4 + 0,75 – 1,25
= 15/4 + 0,75 – 1,25
= (15/4 x 25/25) + 0,75 – 1,25
= 375/100 + 0,75 – 1,25
= 3,75 + 0,75 – 1,25
= 3,25

13. 20/100 + 35/100 = 55/100
=100/100 – 55/100 = 45/100 = 9/20

14. 45 kambing = 25 keranjang
= 45/25 = 1,8
= 45+9 = 54 kambing
= 54 : 1,8
= 30

15. 2,5 m – 16 dm – … = 26 cm
= 250 cm – 160cm = 90 cm
Pita yang digunakan Dita = 90 cm – 26 cm = 64 cm

Maaf klo salah, semoga bisa membantu
