Answer:
3 : 5 : 9
Step-by-step explanation:
The given ratio is
18 : 30 : 54
Rewrite this ratio by writing the factors of each terms as shown below
6×3 : 6×5: 6×9
Now, 6 is common in all the three factors. hence, we can cancel it and we are left with
3 : 5 : 9
Now, there is no any common term. Hence, we can't simplify the ratio more.
Therefore, the required ratio is 3 : 5 : 9
