1. Set up the equation: To convert 23.5 cm to inches, we set up a proportion using the conversion factor:

```
x inches / 23.5 cm = 1 inch / 2.54 cm
```

where 'x' represents the number of inches equivalent to 23.5 cm.

2. Solve for x: To solve for x, we cross-multiply:

```
x inches 2.54 cm = 23.5 cm 1 inch
```

Then, divide both sides by 2.54 cm:

```
x inches = (23.5 cm 1 inch) / 2.54 cm
```

3. Calculate the result: This simplifies to:

```
x inches ≈ 9.25 inches
```

Therefore, 23.5 centimeters is approximately equal to 9.25 inches.
