Convert 25% into a decimal.

• A. 0.15
• B. 0.20
• C. 0.25
• D. 0.30

Answer: (C)

To convert a percentage to a decimal, you divide the percentage by 100. In this case, taking 25% and performing the calculation involves these steps:

1. Start with the percentage value, which is 25.

2. Divide this number by 100: ( 25 \div 100 = 0.25 ).

This straightforward division effectively shifts the decimal point two places to the left, transforming the percent value into its decimal equivalent. Thus, 25% is equal to 0.25 in decimal form, which corresponds with the correct choice given in the question.

Keeping in mind how percentages work is crucial—remember that percentages represent a part out of a whole, and converting to a decimal simplifies numerical operations in mathematics.
