Which of these points lies to the left on the coordinate ray: a) A (2.8) or B (2.4) b) C (0.45)

Which of these points lies to the left on the coordinate ray: a) A (2.8) or B (2.4) b) C (0.45) or D (0.49) c) E (7.85) or K (7.9)

First of all, we note that to the left of the coordinate line is the point whose coordinate is less than the coordinates of all other compared points.

Taking into account the fact we noted above, let us compare all the pairs of points proposed in this task:

1) Point B (2.4) is located to the left of point A (2.8), since 2.4 <2.8;

2) Point C (0.45) is located to the left of point D (0.49), since 0.45 <0.49;

3) Point E (7.85) is located to the left of point K (7.9), since 7.85 <7.9.

Answer: 1) B; 2) C; 3) E.
