What is 30% expressed as a fraction in lowest terms?

Reviewed by Jordan Morley, Editorial Lead at 247SimpleTests. Written by the 247SimpleTests Editorial Team from the official source material cited on every question.

Correct answer

3/10

  1. A 3/10
  2. B 30/10
  3. C 1/3
  4. D 3/100

Why this is the answer

A percent means 'per hundred,' so 30% = 30/100. Reduce by dividing the numerator and denominator by their greatest common factor, 10: 30/100 = 3/10. The fraction in lowest terms is 3/10. The distractor 3/100 omits the reduction step incorrectly (it confuses 30/100 reduction), and 1/3 is a different value (33.3%). To convert a percent to a fraction, write it over 100 and simplify. Here 30% equals 3/10.
