Answer:
I believe the answer is 3/4
Step-by-step explanation:
18 and 24 both have common factors of 6. So you would divide both 18 and 24 by 6. 18÷6=3 and 24÷6=4. 3 and 4 don't have any common factors so this is the lowest it can go and can't be divided anymore. So, 3/4 is the simplest form. Hope I helped! :)
