Answer 1

1. 6/24 + 20/24 + 9/24 =35/24 = 1 11/24
2. ( 7 + 3 + 5 ) (30/40 + 35/40 + 8/40)  = 15 73/40 = 16 33/40
3. ( 5 + 6 +4 ) (8/36 +9 /36 +15/36)= 15 32/36
4. 3/18 - 2/18 =1/18
5. 3 ( 20/24 - 9/24 ) = 3 11/ 24
6. (4 -11 ) ( 12/90 -55/90 ) = 15 (43 /90)
7. (5-2) (7/12 - 2/12 ) = 3  3/12 = 3 1/4
8. (7-4) ( 4/36 - 3/36)= 3  1/36
9.( 9-6 )  ( 85/80 - 52/80 ) = 3 23/80
10. 18 x 13/ 7 = 33 3/7
11. ( 9 :1 ) ( 1/3 x 9/1 ) = 9 3/1 = 9. 3 = 27
12.12 : 2 ( 1/7 x 3/4 ) = 6 3/28
kalo ad salah maaf ya ....
