Step-by-step solution

Here are the solutions to the questions:

1. Look at the number line and answer the questions.

  • a) On the given number line, which rational number does the point A represent?
  1. Observe the number line.

    The segment between 0 and -1 is divided into 4 equal parts. Each part represents 14\frac{1}{4}.

  2. Point A is 3 divisions to the left of 0.

  3. Therefore, point A represents −34-\frac{3}{4}.

    The rational number represented by point A is $\boxed{-\frac{3}{4}}$.
    
    • b) On the number line, find the sum of rational numbers represented by the points A and B.
