Express 3% as a decimal.

Express 3% as a decimal.

• A. 0.3
• B. 0.003
• C. 0.30
• D. 0.03

Answer: (D)

Percent means parts per hundred, so converting a percent to a decimal is like dividing by 100 or moving the decimal two places to the left. For 3%, you have 3 per 100, which is 3 divided by 100 = 0.03. Moving the decimal two places left from 3 also gives 0.03. The other options don’t match: 0.3 represents 30%, not 3%; 0.003 represents 0.3%; and 0.30 is just another way of writing 0.30, which is 30%.
