The answer to the question is 1:4
Step-by-Step explanation:
We have to divide each number over here by the LCF of 15.
The LCF (Least Common Factor) of 15 is 5.
Given the LCF of 15 is 15, we will divide both given numbers by 15.
We will put the numbers back in order from least to greatest.
The ratio we find is 1:4, and the answer to your question is 1:4.
