Which of the following fractions is less than 7/8 and greater than 1/3 ?

  • A.17/24
  • B.23/24
  • C.11/12
  • D.1/4

Answer: A

Put everything over a common denominator of 24 and compare:

\[ \frac{1}{3} = \frac{8}{24}, \qquad \frac{7}{8} = \frac{21}{24} \]

So the fraction must lie strictly between \( \tfrac{8}{24} \) and \( \tfrac{21}{24} \).

  • \( \tfrac{17}{24} \) - between them ✓
  • \( \tfrac{23}{24} \) - above \( \tfrac{21}{24} \)
  • \( \tfrac{11}{12} = \tfrac{22}{24} \) - also above
  • \( \tfrac{1}{4} = \tfrac{6}{24} \) - below \( \tfrac{8}{24} \)

As decimals the answer is 0.708, comfortably between 0.333 and 0.875.
