12
You want to find an equivalent ratio with 2:3. As the question already gives you 8 where 2 used to be, you need to find out what change occurred to get from 2 to 8 (a multiplication of 4). To find the missing part of the ratio, multiply 4 with 3 to get 12.
I think it is A because 7.65/0.5 equals 1.53 and 7.65/2.42 equals 3.16
As -52 and 7 have no common factors, -52/7 is a completely simplified improper fraction. If it were converted into a mixed number, it would be -8 4/7.
