tolong jawab semuanya yaaaa. soalnya mau dikumpulin besok

1) A
36/54 : 18/18 = 2/3

2) B
3/20 × 5/5 = 15/100 = 0,15

3) B
1/2 × 3/3 = 3/6
5/6 × 1/1 = 5/6
2/3 × 2/2 = 4/6
Dari terkecil ke terbesar = 1/2; 2/3; 5/6

4) B
5/14 dari 280
= 5/14 × 280
= 100

5) B
0,24 = 24/100 = 12/50 = 6/25

6) C
35% dari 280
= 35/100 × 280
= 7/20 × 280
= 98

7) B/C
Antara 2/3 dan 7/9
2/3 × 9/9 = 18/27
7/9 × 3/3 = 21/27

8) C
Persen dari 5/8
5/8 × 12,5/12,5 = 62,5/100 = 62,5%

9) C
35 : 2 1/3
35 : 7/3
35 × 3/7
5 × 3 = 15

10) A
7,35 × 12,25 = 90,0375

11) A
6 1/2 - 3 2/5 + 1 3/4
= 13/2 - 17/5 + 7/4
= 130/20 - 68/20 + 35/20
= 62/20 + 35/20
= 97/20
= 4 17/20

12) D
4 1/2 - 2 3/6 : (2 1/2 + 1 1/4)
= 9/2 - 15/6 : (5/2 + 5/4)
= 54/12 - 30/12 : (30/12 + 15/12)
= 54/12 - 30/12 : 45/12
= 54/12 - 30/45
= 9/2 - 2/3
= 27/6 - 4/6
= 23/6
= 3 5/6

13) D
2 1/2 + 25% + 0,25
5/2 + 25/100 + 25/100
5/2 + 1/4 + 1/4
10/4 + 1/4 + 1/4
12/4 = 3

14) B
1 3/4 + 250% - 0,75
7/4 + 250/100 - 75/100
7/4 + 5/2 - 3/4
7/4 + 10/4 - 3/4
14/4 = 3 2/4 = 3 5/10
