Measuring Units Worksheet: Convert meters to centimeters.

Problem Overview:

The task is to convert measurements from metres (m) to centimetres (cm) and vice versa. The key conversion factor is:

$$
1 \, \text{metre} = 100 \, \text{centimetres}
$$

This means:
- To convert from metres to centimetres, multiply by 100.
- To convert from centimetres to metres, divide by 100.

Let's solve each problem step by step.
