To find the width in centimeters given the conversion factor of 1 centimeter being equivalent to 0.393 inches, we need to determine which calculation correctly converts inches to centimeters.

Let's analyze each option:

1. **$$ 0.393 \div 2.5 $$**: This calculation does not represent a conversion from inches to centimeters.

2. **$$ 2.5 \div 0.393 $$**: This calculation would give the number of centimeters in 2.5 inches, which is a valid conversion.

3. **$$ 2.5 \times 0.393 $$**: This calculation would give the number of inches in 2.5 centimeters, which is not what we want.

4. **$$ 2.5 - 0.393 $$**: This calculation does not represent a conversion and is irrelevant to the problem.

The correct calculation to find the width in centimeters from inches is:

$$
2.5 \div 0.393
$$

Now, let's perform this calculation to find the width in centimeters.

I'll calculate $$ 2.5 \div 0.393 $$.
Calculate the value by following steps:
- step0: Calculate:
  $$\frac{2.5}{0.393}$$
- step1: Convert the expressions:
  $$\frac{\frac{5}{2}}{\frac{393}{1000}}$$
- step2: Multiply by the reciprocal:
  $$\frac{5}{2}\times \frac{1000}{393}$$
- step3: Reduce the numbers:
  $$5\times \frac{500}{393}$$
- step4: Multiply:
  $$\frac{5\times 500}{393}$$
- step5: Multiply:
  $$\frac{2500}{393}$$
The calculation $$ 2.5 \div 0.393 $$ yields approximately $$ 6.361 $$ centimeters.

Thus, the width in centimeters corresponding to 2.5 inches is approximately $$ 6.36 $$ cm.

The correct calculation to convert inches to centimeters is:

$$
2.5 \div 0.393 \approx 6.36 \text{ cm}
$$
The correct calculation to find the width in centimeters is $$ 2.5 \div 0.393 $$, which is approximately 6.36 cm.

b) One centimetre is equivalent to 0.393 inches. The calculation required to find the width in centimetres is: \( 0.393 \div 2.5 \) \( 2.5 \div 0.393 \) \( 2.5 \times 0.393 \) \( 2.5-0.393 \)
