The scale in the image runs from 0 to 2, with A and B marked at specific points. The question asks to identify the decimal values corresponding to points A and B on this number line.

Here is the breakdown:

1. The interval between 0 and 2 is divided into 4 equal parts.

   • Since there are 4 divisions, each part represents $\frac{2}{4} = 0.5$.

2. Point A is located at the first tick after 0, which represents $0.5$.

3. Point B is located at the third tick after 0, which represents $1.5$.

Thus:

• Letter A represents $0.5$.
• Letter B represents $1.5$.

Here are 5 related questions to deepen your understanding:

1. How would the positions change if the number line went from 0 to 4 instead of 0 to 2?
2. What is the decimal value of a point exactly halfway between 1 and 2 on this number line?
3. If another point, C, was placed between A and B, what would its decimal value be?
4. How would you determine the value of A and B if the scale had 8 equal divisions instead of 4?
5. Can you convert the values for A and B into fractions?

Tip: Always check how many divisions a number line is split into, as this helps you accurately determine the value at each tick mark.
