Which of the points A (1/2), B (1/9), C (6/7) is located on the coordinate line to the left of the others?

Points that are located on the coordinate ray to the left, they have a smaller coordinate, which to the right have a larger coordinate. Therefore, among the points with coordinates A (1/2), B (1/9), C (6/7), you need to determine the point with the smallest coordinate.
A (1/2) = A (63/126),
B (1/9) = B (14/126),
C (6/7) = C (108/126).
Then point B (1/9) is to the left.
Answer: In (1/9).
