What is a percent?

  1. A ratio whose denominator is 100
  2. A ratio whose numerator is 100
  3. Any fraction greater than 1
  4. A decimal with exactly two digits
Show answer and solution

Correct answer: A. A ratio whose denominator is 100

1. The word percent literally means per hundred. 2. A percent expresses a quantity as a ratio out of 100. 3. A percent is a ratio whose denominator is 100. 4. It is not defined by having 100 as the numerator, by always being greater than 1, or by having exactly two decimal digits. _Source: OpenStax Prealgebra (CC BY 4.0), Ch 6 "Percents", section 6.1 Understand Percent_

How is 44% written as a ratio?

  1. 100/44
  2. 44/100
  3. 44/10
  4. 44/1000
Show answer and solution

Correct answer: B. 44/100

1. The word percent means per 100. 2. Writing a percent as a ratio places the percent number over 100. 3. 44% becomes 44/100. 4. Flipping the ratio to 100/44, or writing the denominator as 10 or 1000 instead of 100, would all misrepresent the original percent. _Source: OpenStax Prealgebra (CC BY 4.0), Ch 6 "Percents", section 6.1 Understand Percent_

What is 36% written as a fraction in simplest form?

  1. 9/20
  2. 6/25
  3. 9/25
  4. 4/25
Show answer and solution

Correct answer: C. 9/25

1. Write 36% as a ratio with denominator 100: 36/100. 2. Both 36 and 100 share a common factor of 4. 3. Dividing both by 4 gives 9/25. 4. 9/20, 6/25, and 4/25 all come from dividing by the wrong common factor, giving fractions that are not equal to 36/100. _Source: OpenStax Prealgebra (CC BY 4.0), Ch 6 "Percents", section 6.1 Understand Percent_
