Convert 7/20 to a percentage.

Convert 7/20 to a percentage.

• A. 35%
• B. 25%
• C. 70%
• D. 45%

Answer: (A)

Converting a fraction to a percentage means expressing the same value with a denominator of 100. So for 7/20, turn it into a decimal first: 7 divided by 20 equals 0.35. Since a percentage is that value times 100%, 0.35 becomes 35%. You can also see this by scaling to a denominator of 100: multiply top and bottom by 5 to get 35/100, which is 35%. The other options correspond to different fractions (for example, 25% is 1/4, 70% is 7/10, 45% is 9/20), so they don’t match 7/20.
