7) 1. Divide all by common factor 6.
U got the ratio 18:30:12 correct.
But u need to simplify it to simplest form by dividing them by a common factor.
If u dont know what is the highest common factor..
U can try dividing it by 2 first since all are even numberd..
So it becomes 9:15:6
Then further simplify it by dividing them by 3.
So 3:5:2
