What part of a revolution have you turned through if you stand facing
west and turn clockwise to face east ?

Answer

To determine what part of a revolution you have turned through when facing west and turning clockwise to face east, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Directions**:
- When you are facing west, you are looking towards the left side of the compass.
- The directions are arranged as follows: North (up), East (right), South (down), and West (left).

2. **Identify the Turn**:
- To turn from west to east, you need to rotate clockwise.

3. **Calculate the Degrees of the Turn**:
- A full revolution is 360 degrees.
- To turn from west to east, you need to go through the following angles:
- From west (270 degrees) to north (0 degrees) is 90 degrees.
- From north (0 degrees) to east (90 degrees) is another 90 degrees.
- Therefore, the total turn is 90 degrees + 90 degrees = 180 degrees.

4. **Determine the Part of the Revolution**:
- Since a full revolution is 360 degrees, the part of the revolution you have turned through is:
\[ \text{Part of revolution} = \frac{\text{Degrees turned}}{\text{Total degrees in a revolution}} = \frac{180}{360} = \frac{1}{2} \]

5. **Conclusion**:
- You have turned through half of a revolution.

### Final Answer:
You have turned through **1/2** of a revolution.
