Let's solve the problem step by step.

The task is to determine how many centimeters (cm) each arrow points to on a ruler that measures from 0 to 15 cm. The ruler includes half-centimeter markings, so we need to pay attention to whether the arrow points exactly on a whole number or halfway between two numbers.

---

Understanding the Ruler:

- Each large mark represents 1 cm.
- Each small mark between two large marks represents 0.5 cm (half a centimeter).
- So, for example:
- Between 0 and 1: the small mark is at 0.5 cm
- Between 1 and 2: the small mark is at 1.5 cm, etc.

We’ll go through each row:

---

1st Row:

Arrow points just after 1, but not quite at 2.
It’s pointing at the first small tick after 1, which is 1.5 cm.

✔ Answer: 1.5 cm

---

2nd Row:

Arrow points at 3 — it's directly on the large mark.

✔ Answer: 3 cm

---

3rd Row:

Arrow points at the small tick between 2 and 3, which is 2.5 cm.

✔ Answer: 2.5 cm

---

4th Row:

Arrow points at the small tick between 5 and 6, which is 5.5 cm.

✔ Answer: 5.5 cm

---

5th Row:

Arrow points at 11 — it's directly on the large mark.

✔ Answer: 11 cm

---

6th Row:

Arrow points at the small tick between 4 and 5, which is 4.5 cm.

✔ Answer: 4.5 cm

---

✔ Final Answers:

1. 1.5 cm
2. 3 cm
3. 2.5 cm
4. 5.5 cm
5. 11 cm
6. 4.5 cm

📝 Summary:

You read the ruler by:
- Looking at the whole number the arrow is near.
- Checking if it's on a large line (whole cm) or a small line (half cm).
- If it's between two numbers and on the small line, it's .5 cm more than the lower number.

This helps students understand measuring with precision using halves of centimeters.
