3 out of 25 = 12 out of 100
3 out of 50 = 6 out of 100
2 out of 25 = 8 out of 100
12 + 6 + 8 = 26
100 - 26 = 74%
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.
Number 5 is muply by 2 and number 6 is added by 6
