Explanation:

1. Reading the Ruler:
- The larger markings represent centimeters (cm).
- The smaller markings between each centimeter represent millimeters (mm).
- There are 10 millimeters in 1 centimeter.

2. Converting Measurements:
- If the arrow points exactly on a centimeter marking, the measurement is in whole centimeters.
- If the arrow points between two centimeter markings, count the number of millimeters past the nearest centimeter marking and convert to decimal form (e.g., 35 mm = 0.35 cm).

3. Recording the Answer:
- Write the answer in the format requested (e.g., 0.2 cm, 3.0 cm).
