Tolong jawab yang bawah pake caranya ya kak

9.) 1 3/5 = 1,600
1 2/3 = 1,666
1,65 = 1,650
162% = 1,620
1625/1000 = 1,625
Jawab = A

10.) 2 1/3 -7/9 -5/6
= 7/3 - 7/9 - 5/6
= 42/18 - 14/18 - 15/18
= 28/18 - 15/18
= 13/18
Jawab = D

11.) D:M:A = 3:5:7
Selisih D&M = 80
A = perbandingan A/selisih perbandingan D&M × 80
= 7/2 × 80
= 280

Mohon maaf jika ada yg salah..ごめんなさい。。
