Answer:
A) 72 and 114
Explanation:
The method I used was the process of elimination. Let's look at all the options and filter some out.
Option B, the two numbers are multiples of 5, meaning they can both be divisible by 5, which means that they are not relatively prime.
Option C, both numbers can be divisible by 3, meaning that they are also not relatively prime.
Option D, both numbers can also be divided by 3, meaning that they are not relatively prime.
The only option is A which is the answer.
