Official Solution:Which of the following fractions is the largest?A. \(\frac{11}{27}\)
B. \(\frac{4}{9}\)
C. \(\frac{1}{3}\)
D. \(\frac{25}{81}\)
E. \(\frac{3}{20}\)
Clearly, \(\frac{3}{20}\) is the smallest fraction. Therefore, we should focus on comparing the other four. Using a common denominator of 81 for these fractions, we have:
A. \(\frac{11}{27}= \frac{33}{81}\)
B. \(\frac{4}{9}= \frac{36}{81}\)
C. \(\frac{1}{3}= \frac{27}{81}\)
D. \(\frac{25}{81}= \frac{25}{81}\)
From the above, it's evident that option B represents the largest fraction.
Answer: B
