How can 4% be expressed as a decimal?

1. 0.04

2. 0.40

3. 0.14

4. 0.10

The correct answer is: 0.04

To express a percentage as a decimal, you divide the percentage by 100. In this case, to convert 4% to a decimal, you can perform the calculation as follows: 4% can be written as \( \frac{4}{100} \), which simplifies to 0.04. This is because dividing by 100 effectively shifts the decimal point two places to the left. So, 4% expressed as a decimal is 0.04, which aligns with the provided answer. This method of conversion is fundamental in mathematics, especially when dealing with proportions and financial calculations.
