In this image, we are given a number line and asked to identify a decimal and a fraction (or mixed number) for each of the labeled points: A, B, C, and D.

Let's identify each point:

• Point A:
  Point A is exactly halfway between 0 and 1.
  Decimal: $0.5$
  Fraction: $\frac{1}{2}$

• Point B:
  Point B is the midpoint between 0.5 and 1, which is three-fourths of the way from 0 to 1.
  Decimal: $0.75$
  Fraction: $\frac{3}{4}$

• Point C:
  Point C is exactly at 1 on the number line.
  Decimal: $1.0$
  Fraction: $1$

• Point D:
  Point D is at 1.5, which is halfway between 1 and 2.
  Decimal: $1.5$
  Fraction: $1 \frac{1}{2}$ or $\frac{3}{2}$

Would you like more details on any specific point, or have any questions?

Here are 5 follow-up questions:

1. How can you convert a decimal like 0.75 into a fraction?
2. Why is 0.5 equivalent to $\frac{1}{2}$?
3. What is the significance of mixed numbers, like $1 \frac{1}{2}$?
4. Can fractions greater than 1 be simplified into mixed numbers? How?
5. How can you read a number line to determine exact fractional values?

Tip: Always reduce fractions to their simplest form by dividing the numerator and the denominator by their greatest common factor (GCF).
