Answer:
R
Step-by-step explanation:
The line is divided into eighths which tells you you will have to convert your fraction in the end. 3/4 is close to 1 so it's best to start closest to 1 and work your way back. Point S is the closest but it is 7/8, that doesnt simplify so you have to go lower. R is 6/8, that does simplify down to 3/4, giving you your answer.
