Answer:

7 : 8 : 9 = 21/2 : 12 : 27/7

Explanation:

GIVEN ; 7 : 8 : 9 = ? : 12 : ?

7/24 : 8/24 : 9:24 = ? : 12/x : ?

8/24 = 12/x

x = 12 × 24/8

x = 36

therefore the other two ratio's are

7/24 = ?/36

? = 36 × 7/24

? = 21/2

and

9/24 = ?/36

? = 36 × 9/24

? = 27/2

im not quite confident with this answer, but i hope it helps!
