What is 5% of 100?

• A. 50
• B. 5
• C. 0.5
• D. 10

Answer: (B)

5% means five parts out of one hundred. Convert to a decimal: 5% = 0.05. Multiply by 100 to find the portion: 0.05 × 100 = 5. So five is the result. (You can also see 5% as one-twentieth of 100, and one-twentieth of 100 is 5.) The other values would come from different percentages: 50% would give 50, 0.5% would give 0.5, and 10% would give 10.
